PERENCANAAN DINDING PENAHAN TANAH (STUDI KASUS : JALAN LINGKAR BARAT DURI)

Abstract

The method of processing data from the ucs test results using Sni 3638 - 2012 and planning of gravity type retaining wall and cantilever calculating active and passive ground pressure with soil that has cohesion value (c) using rankine theory and soil support stability using the Hansen method.Based on the results of soil test in proleh value for the weight of volume of timbunan 1 2.070 t/m3 with cohesion value of 7.58 t/m2, heap 2 weight volume of 1.995 t/m3 with cohesion value 3.014 t/m2 and the original ground volume weight 2,023 t/m3with cohesion 6,20 t/m2Gravity wall dimension with wall tread width of 3.05 m, wall height of 2.7 m with foundation tread thickness of 0.4 m and wall width of 0.6 m for cantilever wall tread width of 3 m, wall height of 2.7 m with thickness 0.25 m foundation footprint and 0.6 m wide upper wall. gravity security stability, 2,072 bolsters, 2,007 shear, 7,594 soil support and cantilever security stability, 2,074 bolster, 2,0016 shear and 7,456 soil support. Total gravity wall costs Rp 324.905.941 and cantilever Rp 1.194.985.984. Based on the results of planning the retaining wall that should be used is a gravity type retaining wall, this is due to the higher safety value and lower cost when compared to cantilever type retaining walls.
