ANALISIS STABILITAS LERENG BOJA – DARUPONO STA. 10+720 JAWA TENGAH DAN USULAN PENANGANANNYA
ABSTRACT: The landslide
occurred on road Boja – Darupono Sta. 10+720 created a long traffic jam and
holding up economic development between Kendal and Semarang. By analyzing the
slope stability by using Fellenius method, it is shown that the SF or safety
factor of the slope is 1,19 for the radius of the circle ( R ) = 28,67 and 1,63
for R = 27,09. While SF on a Plaxis V.8.2 program is 1,19, so it can be
concluded that the slope in critical condition because of the SF on Plaxis
V.8.2 program smaller than that of 1,5 safe although the safety factor on
Fellenius value is greater than the value of safe SF. The first alternative of
slope reinforcement is a Bored pile, the second alternative is Geotextille with
a Counter weight. Based on finite element method calculation using Plaxis V.8.2
program, reinforcement with Bored pile produce SF = 1,75 and Geotextille with a
Counter weight SF = 1,5. This form these two alternatives, Bored pile
reinforcement has the greatest, so can be considered as the best alternative
solution.
