Abstract

Landslide is a natural disaster that often occurs in Lampung Province, particularly in WestLampung regency. The sliding occurs due to an increase in soil pore water stress in the rainyseason. Based on the research on the slopes, there is a safety factor value that can be used as areference for the degree of slope stability. One method to analyze the value of slope safety factoris by using the Geostudio Slope / W 2007 program.In this study, some cross sections of slope were simulated with 4 different water table conditions.The required soil properties index are: cohesion, c; natural angle of repose, φ; and unit weight ofdensity, γ .The analysis result shows that slope transversal cut shape have influence on slope stability. Theanalysis results on slopes with saturated conditions have a safety factor value of <1.25 and areclassified on unsafe slopes. In the unsaturated condition the whole simulation is classified as astable slope with a safety factor value> 1.25. Based on the analysis result, it can be inferred thatthe slope has insecured status. Thus, it is suggested to conduct such actions in order to preventlandslide.Key words : soil, slope stability, safety factor, geostudio slope/w.

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.

Abstract

There are several factors that effect the level security of a slope. Such as the condition of a slope with large loads, steep slope and heavy rain condition. The landslide and slope would often occurs on some double track lines on Martapura – Baturaja train because of this things. Therefor, the reinforcement is needed so that the slope is more stable around the slope. The results of physical and mechanical properties of the soil are based on the results of laboratory tests and research in the field. so the PLAXIS program was used in analyzing the stability of the existing slope based on the data. From the results of the program calculation shows that the condition of the slope is not stable. because the safety value indicates 0,89 for saturated conditions and 0,67 for dry conditions and 0,91 for partially saturated conditions. Furthermore, slope stability analysis who was reinforced by a combination of soil retaining wall and borepile. there has been an increase in safety value of 1,30 for saturated conditions, 1,66 for dry conditions and 1,65 for partially saturated conditions. This shows that the slope is stable and the reinforcement design is safe and able to withstand landslides. Keywords : Analysis of Slope On Sandy Clay

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

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

Physical properties of organic soils have a very high water content and low carrying capacity.One method to increase the carrying capacity of the soil is by adding or mixing with materials thathave a high carrying capacity. By adding sand on the sample in this study is expected to increasethe carrying capacity of organic soils of compressive strength and strong shear. The study wasconducted in the laboratory of Soil Mechanics Faculty of Engineering, University of Lampung, bymaking a sample of the results of compaction standard, then the samples are given the addition ofsand to the percentage increments of 5%, 10%, 15%, and 20% for the comparison of thecompressive strength (qu), shear angle (φ), and the value of cohesion (c) after the addition ofsand.Results of testing the compressive strength and shear strength showed soil behavior in a state ofthe sample with the addition of sand up to 20% has an increased qu and φ, but a decline in thevalue of soil cohesion. The more increasing mix of sand in the soil samples, the values ofcohesion / coherence on the ground will be more decreased, but the sand has good gradation andstrong grain will be able to withstand the load that works vertically or horizontally.Keywords: Organic Soil, Compressive strength and Shear strength, Friction Angle, and Cohesion.
