Abstract

This Final Project contained about land stability and it countermeasures on roads Cening Sub-district of Singorojo District of Kendal Central Java. This road crosses the hills with unstable soil conditon. Based on the soil drilling test result, it’s contain of  clay, clay stone ( splinter ), and clay stone ( clay shale ) layers. This Final Project analyzes value of the slope safety factor that included a condition when occured of the movement of soil slopes which is caused by instability on slopes due to degdradation of soil layers, manual calculation of slope stability using Fellenius method and Plaxis V.8.2 computer program. Based on the to manual calculation of slope stability using Fellenius method,it’s obtained value of the slope safety factor equal to 1,074 and use Plaxis software obtained value of the slope safety factor equal to 1,081. Those values of the slope safety factor are still less than slope stability regulation equal to 1,5, with the result that the slope condition is prone to landslide. The Analysis result indicate that reinforcement slope with bored pile with diameter of 0,55 m in depth of five meters which is placed at the bottom of the slope, it’s the alternative handling had increased the value of the safety factor with the factor of safety of the existing condition which is from 1,081 become 1,812.

Abstract

The aim of this thesis was to analyze the slope stability on clay shale soil and to provide recommendations of design that meet the design criteria with the level of service based on the standard on the project Semarang-Solo toll road. The toll road was built to support economic growth in Semarang, Solo and its surroundings. The location was reviewed in this thesis include a toll road project Semarang-Solo package IV Sta. 22+700 to 22+775. We choose these location because we consider that these sta have the greatest risk of landslides. The data used in this case study were primary and secondary datas. The datas were collected by interview method, observation methode and methods of literature. For analysing in this thesis were by calculate the slope stability and provide alternative solutions to problems that occured. Geotechnical analysis was done in two ways, namely manual and program. Manual analysis used Fellenius method and Bishop’s method while analysis finite element method used Plaxis software 8.2. Mohr-Coulomb failure model were chosen as a model soil. The results showed that the catastrophic landslide occurred at Sta 22+700 to 22+775. Changed the geometry of the slope and strengthening with bored pile at two different elevation were tired to produce sliding safety factor 1,433 this value is greater than the safety factor requirement 1,4.
