Abstract

The Mota'ain-Motamasin road section is a road section that was built in the realization of infrastructure development in the border area in East Nusa Tenggara which borders Timor Leste. On this section, road construction has been completed, but at several points there are landslides that need to be addressed. Research conducted includes modeling and testing in the laboratory. Physical, mechanical, suction and XRD tests were carried out on the samples. Back analysis was carried out to obtain soil parameters during landslides. Then analyzed the stability of the slopes Sta 149+140 with deterministically and probabilistically and analyzed the sensitivity of soil parameters to the value of Safety Factor. Bobonaro soil is classified as Cohesive Soil and has a value of    Liquid Limit = 80.823% and Plasticity Index value = 58.747%, classified as CH (High Plasticity Clay) soil. Bobonaro soil has kaolinite content of 3.4%-17.9%, illite 16.6%-42.6%, and montmorillonite 9.6%-30.6%. The combination of small amount of kaolinite and high montmorillonite accompanied by high changes in water content is the cause of frequent landslides on the mota'ain-motamasin roads. At Sta 149+140, the value of Safety Factor = 1,249 at GWT 0 m becomes SF = 1,254 at GWT -5 m probabilistically 10,000 iterations. The value of SF = 1,254 without suction becomes SF = 1,263 when there is suction at GWT -5 m probabilistically 10,000 iterations. The most sensitive soil parameter on the Safety Factor is cohesion, followed by the internal shear angle and unit weight. Handling of Sta 149+140 landslides used bore piles with SF=1.808 > SF=1.5.

Abstract

On the Ende-Kelimutu national road section at STA 8+425, according to the identification and field survey, the landslide that occurred at this point was caused by high rainfall intensity and geological factors of the slope. As the road supervisor, the Balai Pelaksanaan Jalan Nasional (BPJN) of East Nusa Tenggara has designed a landslide treatment using a combination of cantilever walls and drilled poles. Soil investigation data at STA 8+425 shows that the slope is dominated by sand with N-SPT values above 15 to a depth of 14.45 meters. When making design improvements, a number of rainfall data from several weather observation stations are needed, in order to determine the effect of rainwater infiltration on the landslides that occur. This study aims to determine the influence of rainwater infiltration on the occurrence of landslides at the study site, where the results of the analysis conducted with Geostudio prove the truth. Modeling with the combination of SEEP/W and SLOPE/W, the FS value before the landslide was 2.302 and then decreased to 0.35 during the landslide.

Abstract

On the Sicincin-Padang toll road section there are several geotechnical problems, one of which is that at the Sta 10+250-10+400 is dominated by an organic soil. In the implementation of a 4.0 meter high embankment there are cracks appeared on the left side of embankment toe. Based on the evaluation results of monitoring geotechnical instruments in the field, the cracks that occur can be caused by the bearing capacity failure or due to the implementation stages of embankment construction is too fast. The method used in this research is to use finite element method by numerical simulation using Plaxis 2D program to determine the stability of embankment slope stability acording to the stages of implementation in the field and by modeling a staged construction, where the speed of embankment construction depends on the thickness of the embankment layer used, which is 15 cm to 25 cm until the design height is reached and the consolidation time is 1 day to 14 days for each additional 1 meter of embankment height. The porpose of this study is to determine the stages of implementation that are safe and compliant with the design criteria requrements.From the modeling results the existing embankment construction in the field has a safety factor value of SF=1.156. In this research, variations in the construction stages that have been modeled were obtained that are safe and meet the design criteria at the location under review are; at Sta 10+250 with using 25 cm thickness fill layer and 14 days consolidation time, Sta 10+350 with a 15 cm thickness fill layer and 7 days consolidation time, Sta 10+400 with a 25 cm thickness fill layer and 5 days consolidation time. There are differences in the effective time at each of the locations reviewed, this is due to differences in geometric embankment conditions at each location. From the results of modeling analysis, it also found that by reducing the thickness of the embankment fill layer and increasing the consolidation time, the value of the safety number will increase, the amount of settlement will increase, the amount of lateral movement will decrease and the excess pore water pressure will decrease.

Abstract

Clay shale consists of thin, layered formations with irregular fractions, highly smooth, and easily separable along the layer planes. If Clay shale is exposed to sunlight, air, and water for a relatively short period, it will undergo weathering. The construction of the Serang - Panimbang Toll Road Section III is carried out by cutting the soil according to the planned contours. After the cutting process, the subgrade material undergoes a change in its characteristic properties and mechanics because the subgrade soil is Clay shale material that has weathered, commonly referred to as "Weathered Clay Shale." To transform this soil into a subgrade layer that meets the requirements, stabilization with Ca(OH)2 lime is necessary; in this case, the percentage of lime and the duration of curing need to be determined to achieve optimum lime content.The soil material used is Weathered Clay Shale obtained from the Serang - Panimbang Toll Road Section III STA 57+200. The research involves identifying the initial soil properties, conducting standard proctor tests on soil mixtures with lime variations of 4%, 7%, and 10% to determine the most optimum soil-lime mixture with Ca(OH)2. Subsequently, soil properties are identified with the most optimum lime mixture, and soaked CBR tests are conducted on the optimum lime-soil mixture with curing time variations of 0, 7, and 14 days.The 7% Ca(OH)2 lime mixture with weathered clay shale soil at STA 57+200 in the construction of the Serang-Panimbang Toll Road Section III has achieved sufficiently good bearing strength. The bearing capacity attained has exceeded the requirements of the Bina Marga Specifications Revision II, especially during the 14-day curing period, where the achieved bearing capacity significantly surpasses the specified standards.

Abstract

Aggregate material for road subbase layers that meet specifications is hard to find in Kalimantan Island. One alternative material is a mixture of fly ash and bottom ash (FABA) with the addition of other substances such as lime or cement as binders. It is essential to determine the optimum percentage of the fly ash, bottom ash, and lime or cement mixture to meet the requirements as road subbase material. This study was conducted by creating compositions of FABA with variations 100:0; 75:25; 50:50; 25:75; and 0:100; they were tested to determine the optimum mixture of FABA as a road subbase. Afterwards, additional materials that were cement (3%, 5%, and 7%) or lime (2%, 4%, and 6%) were added to the optimum mixture of FABA; and then, they were tested to obtain the subbase material that meets the requirement of Bina Marga specification criteria. The results show that the optimum FABA material mixture is 50:50 which has the soaked CBR value of 17.03%. Additional 7% of cement or 6% of lime give the highest values of soaked CBR and UCS. For cement, the soaked CBR value is 75.68% and the UCS value is 21.448 kg/cm2; for lime, the soaked CBR value is 60.16% and the UCS value is 27.70 kg/cm2. Based on Bina Marga specifications, SKh 1.15.1, it is known that the FABA mixture 50:50 ratio and the additional of 7% cement or 4% lime can be uses as road base materials.

Abstract

The slopes of the Awunio - Lapuko national road section are prone to landslides, which pose a threat to the road asset management. Hard soil layer with an NSPT value >60 is found at a depth of 4 metres. The slope has been reinforced with cantilever walls (CW) and caisson as well as retaining walls and bored pile. In this research, the problem that needs to be studied is the stability of the existing slope with and without reinforcement using the cracked soils approach to obtain the factor of safety (FS) for critical conditions with the Limit Equilibrium Method (LEM). The CW is calculated for overturning stability, shear stability, foundation bearing capacity and overall stability. In addition, bored pile should also be evaluated when considered as a lateral pile based on NAVFAC, bearing capacity within the group, max & min stress and deflection capacity.  The result of  LEM program analysis shows the slope failure mechanism due to the existence of slip plane between weak soil layer and strong soil layer. Furthermore, the stability of existing reinforcement such as CW only or CW combined with caisson is insufficient. While the stability of reinforcement CW combined with bored pile or alternative modification such as subdrain combined with geotextile meets the requirements.
