Abstract

Soil landslide is one of the most common in the field of Geotechnical due to increased shear stress of a soil mass or decrease in shear strength of the soil mass. In other words, the shear strength of the soil mass is not able to bear the burden of work going on. Disruption to the stability of the slope can be caused by various human activities and natural conditions. Unstable slopes is dangerous to the surrounding environment, therefore slope stability analysis is needed. In this case the condition of Padang Tambak – Liwa street KM.227+400 Lampung Barat experience landslide up the road. The purpose of this study is to evaluate the value of the safety factor and to plan the dimension and stability of sheet pile to the landslide on Padang Tambak – Liwa street KM.227+400 using the Plaxis v.8.2 of computer program. The result of this study obtained the value of safety factor at the initial condition of 0,7106, with displacement of 12,71 x 103 m. The handling of reinforcement slopes of sheet pile profiles of type OT26 U profile which is placed at 2,5 meters from the middle of the highway with a size of 12 meters and then replace the soil layer 1 on the outside of the sheet pile into a slope-like slope soil and reduce the slope to 32° level obtained factor value safety at 1,1532, with displacement of 145,88 x 10-3 m. Handling by reinforcing sheet pile profiles of type OT26 U profile in this condition was considered safe because it met the requirement of safety factor value and had a small displacement value.Keywords: slope stability, safety factor, plaxis, sheet pile, displacement.

Abstract

Soil permeability value for every construction is different. Such differences affect the strength of acivil construction to be built. Therefore it is necessary to attempt to manipulate the soilpermeability value by adding the additive to a soil permeability values obtained in order to meetthe standard of civil construction to be built. Among the many additives are used as soilstabilization materials, one of them is rice husk ash. Some recent researches in the field of CivilEngineering showed that rice husk ash mixture useful as a particularly clay soil stabilization.Because rice husk ash can fill the cavities that exist between the grains of ground.Soil samples tested in this study is clay derived from Perumahan Bhayangkara, KelurahanBeringin Jaya, Kecamatan Kemiling, Bandar Lampung. Rice husk ash used were obtained fromDusun Dantar, Kecamatan Padang Cermin, Kabupaten Pesawaran. This study was conducted todetermine the effect of rice husk ash to the soil permeability values.The results of analysis and calculations performed in the laboratory obtained averagepermeability value (k) for soil with 5% rice husk ash added, 10% rice husk ash added, and 15%rice husk ash added. The permeability value used to be compared with native soil (clay).Key words: clay, rice husk ash, permeability.

Abstract

This study aims to see the influence the fraction of clay in the sand by comparing parameters ofstrong shear soil that is resulted from unsoaked and soaked conditions of Direct Shear Test andAtterberg Limit. An increase in the fraction of clay in the sand can change the physical propertiesof the soil and the mechanical properties. An increase in the fraction of clay can also improve thevalue soil cohesion and ground plasticity index but it reduces the value soil friction. Theparameter change magnitude is analyzed by looking at the results of correlation analysis ofcohesion of the soil plasticity index, and some of the physical parameters of the soil. Thecorrelation between the shear test directly with the plasticity index against the physical propertiesof soil clays that linear regression obtained a very strong correlation (0.8 – 1) and limit land thatis used are sand which is already substituted by clays from 0% – 50%.Direct shear test which results from the condition of unsoaked conducted in the laboratoryobtained that addition levels of clay showed an increase in the value of cohesion but the angleshear declined. Direct shear test results from the condition of soaked (soaking 4 days) obtained adecrease of the value of cohesion (c) down and slide angle (φ) which is also affected by soakingthe soil. The test results show the Atterberg limits that a percentage of the original soil andaddition of clays to 20% has no plasticity index value. This is because the ground is still are off(loose soil). As for the addition of clays from the percentage of 30%, 40%, and 50% of the land isincluded soil cohesive and value each PI is 8.87%, 17.7%, and 12.04%.Keywords: direct shear, cohesion, plasticity index

Abstract

One of the causes of construction failure on asphalt pavement is segregation. Which  is the separation of small and large aggregate grains within a mixture, so that in a part of the coating of the pavement will be concentrated aggregate coarse and in other part will be concentrated fine aggregate. One of the factors causing segregation is the hauling distance from Asphalt Mixing Plant to the slap location. To understand this, task a study on the impact of the transport process on segregation on hot asphalt mixture from Asphalt Mixing Plant to the location of the spread. The mixture used is the Asphalt Concrete-Wearing Course type or the laston coated wear of Asphalt Mixing Plant PT. Gigging Polah Raya for work location which is 28.9 km on Jalan Sultan Agung, Bandar Lampung, Lampung and PT. Rindang Tigasatu Pratama for work location located 53.3 km on Jalan Teuku Cik Ditiro, Bandar Lampung, Lampung. Examination of sample is done trough extraction test and sieve analysis test. From the result of the research, it’s found that there is being segregation during the transport of asphalt mix mixture from Asphalt Mixing Plant to the slap location. For sample PT. Manggung Polah Raya, gradation aggregate is still within the upper and lower limits of the general specification Bina Marga 2010. As for the sample of PT. Rindang Tigasatu Pratama, the aggregate gradation is out of the upper and lower limits of the general specification of Bina Marga 2010. Factors affecting segregation are haulage distances and aggregate density. Keywords: Road Pavement, Asphalt Concrete, Segregation.

Abstract

ABSTRACTThe soil layer is the bottom layer that has function to forward the load from construction on it. But not always the basic soil layer is able has function properly as the bearing capacity. The soil stabilization method with lime additive is an alternative that can be used in planning on a unstable soil construction. The aim of this research is to know the physical characters of clay soil in Sidodadi Asri area, Jati Agung subdistrict, South Lampung regency and the type of silt soil in Yosomulyo area, East Metro District, Metro City. And also to know the increase of the bearing capacity of both types of soil with variation of curing time of 7, 14 and 28 days. From the result of the physical character research and mechanical of original soil samples obtained so it can be concluded that land taken from Sidodadi Asri village classified as clay with high plasticity, while the soil from yosomulyo village is clay with low plasticity. And on the CBR test in the ideal soaking conditions with ideal lime content showed that the increase of CBR value in each soil type along with the increase of the curing duration of 2.8%, 4%, 6.4% and 10.2% in clay and 2, 2%, 3%, 3.6% and 6% in silt soils. This suggests that the ideal lime composite in addition to the curing duration gives a positive effect to increase bearing capacity soil or CBR value. Keywords: Lime, Stabilization, Clay and Silt Soil, Soaked CBR.
