Abstract
The bearing capacity of the soil is the ability of the soil to withstand the pressure or load of the building on the soil safely without causing shear collapse and excessive settlement. In the case study at sta 1+035 IC, it is known that the bearing capacity of the soil is low. The lack of bearing capacity of the subgrade at that location causes two problems, the first is due to the height of the embankment reaching 10 m, which will cause landslides and collapse of the bearing capacity of the subgrade. To overcome this condition, mechanical repairs are carried out to minimize the occurrence of landslides. In this research I used geotextile reinforcement. The method used in this research is quantitative method with Bishop method manually and also with XSTABLE application to describe the landslide plane and SF that occurs. The data used are secondary data and reference data correlation with geotextile calculations using 2 different types of Woven Geotextile Mirafi PET 100 - 50 and 200 - 50. From the results of analysis and calculation obtained (SF) that occurs in the 10 m high soil without reinforcement is 0.701 (soil without load), 0.688 (soil plus structural load), 0.694 (soil plus truck load), 0.624 (soil plus earthquake load), and 0.548 (soil plus all loads). The maximum embankment height that can be done without reinforcement is 2.51 m high with SF 1.5 and the number of geotextile layers required is if the geotextile specification used is woven type 100 - 50 with Sv 0.2 m, there are 46 layers with layers 1-34 using 2 sheets of geotextile. As for the specification of geotextile woven 200 - 50 with Sv 0.25, there are 32 layers with layers 1-5 using 2 sheets of geotextile and Sv 0.4m 25 layers with layers 1-17 using 2 sheets of geotextile.
