Abstract

Landslide are one of the natural disasters that often occur during the rainy season. As in the area of Bukit Barisan Selatan National Park, Lampung Barat, which is a road that is always passed many vehicles. This happens because of an increase in pore water pressure on the slope, which then resulted in a decrease in shear strength (c) and friction angle (φ). Required slope stability analysis and prevention of sliding slopes experiencing.One of the slope stability analysis method used is Fellenius with countermeasures using retaining wall. Fellenius slope stability analysis method (1927) considers the forces that work on either side of any resultant slices have a zero in the direction perpendicular field of avalanche. Fellenius method provides a safe factor is relatively lower than a matter of a more thorough way.From the analysis of slope stability, slope expressed in critical condition. Countermeasures sliding slope using stone retaining wall plug and using gabion. Dimensions and gabion retaining wall that has been planned can be applied in the field so that avalanches do not occur again. Keywords: slope stability, safety factor, fellenius, retaining wall, gabion.

Abstract

The subgrade is a very important role in road construction because it is the beginning of determining the quality and capacity of the soil bearing capacity. One way to strengthen the soil is by soil compaction because it can reduce the amount of unwanted soil subsidence and to rearrange the soil grain structure, so that it becomes denser so that the soil will be denser.This study used grained soil, the type of silty sand from Muara Dua Village, Ulu Belu District, Tanggamus Regency, Lampung Province. The method used is standard compaction and laboratory CBR to determine the impact of the pressure value using a modified press device. The burden used in this research is 3 MPa, 6 MPa, 9 MPa, 12 MPa, and 15 MPa.In the modified press tool test, the values obtained were 12.1 MPa and Laboratory CBR for 3 MPa pressure was 2.7%, 6 MPa pressure was 3%, 9 MPa pressure was 7.8%, 12 MPa pressure was 12.3%, and pressure 15 Mpa of 15.9%. So it can be concluded from the impact of the pressure value using a modified press tool is that the greater the pressure value, the CBR value will increase.Keywords: Standar Proctor, CBR Laboratory, Modification Press Tool.

Abstract

This study was conducted to determine the behavior of reduction and compressive strength in claywhich is substituted with sand material and to see the correlation between the value ofconsolidation and the compressive strength on the soil. Because the clay when getting loadingthere will be a significant reduction in soil that affects the reduction in carrying capacity orcompressive strength of the soil. In this study used clay from the village of Belimbing Sari, Jabungdistrict, East Lampung with the coordinates of 105° 39 '10.74 "T and 5 ° 31' 44.26" S.The research was done by testing on samples without a mixture of clay and the clay soil mixedwith sand with varying amounts of sand mixture of 10%, 20%, and 30%. Testing was conducted ona standard compaction test to find the optimum water content, consolidation testing to find thevalue of the coefficient of consolidation (Cv), compression index (Cc) and coefficient ofcompression (Av) and compressive strength testing are free to seek the compressive strength on thesoil.Based on the results of this study can be seen in the behavior of a mixture of clay and sand withoutonce mixed with sand material that is an increase in the value of the coefficient of consolidation(Cv), a decrease in the value of compression index (Cc) and coefficient of compression (Av) and anincrease in the compressive strength (qu) in the clay soil. Value increases and decreases that occurwithout a mixture of clay and after mixed variations mixture of 10%, 20%, and 30% tend to bestable. From this study it can be concluded that the value of consolidation and strong correlationpress substituted clay with sand material that is smaller then the consolidation of soil compressivestrength will be greater as well.Keywords: Soil Clay, Sand, Consolidation, Soil Compressive Strength
