Abstract

Puncak Pass STA. 20+650, it’s a hills area with land use change condition but there’s no different or change topography. The main causes landslide in Puncak Pass. There’s assessment like building and street in the top of slope that causes a bigger landslide it even hapen twice. There’s a lot of causes impact like break the highway and collapsed building. This study task is about handling the landslide with such condition finite element method analysys and plaxis program for analysys the deformation geotechnic stabilition in analysys handing landslide. There’s a secure system on the analysys results (Msf) 1,112. The results of analysys of ten safety factors with gabion dan pile combination 1,845 in normal condition, if there’s earthquake the safety factor will touch 1,244. Recommendations for a landslide in Pucak Pass area is combinations of gabion and pile that meets the design criteria.

Abstract

A bridge is the main infrastructure that connects two parts that are cut off due to an obstacle that cannot be built conventionally. To expedite and facilitate land transportation, bridges are needed to connect one region to the next. The foundation is one part of building construction which functions to place the building and transmit the load distributed from the upper structure to the foundation soil which is strong enough to support it without differential settlement occurring in the structural system. At this project location, a type of suspension bridge was chosen using a Strauss pile foundation. The aim of this research is to analyze the bearing capacity and settlement of foundations based on Standard Penetration Test (SPT) data, laboratory tests and sondir/Cone Penetration Test (CPT). In this study, the depth and diameter used are the same, the only difference is the method used. Based on the analysis results, the bearing capacity value using N-SPT data was 2021.72 kN, while the permit carrying capacity value using Laboratory and Sondir data was 1108.98 kN and 804.71 kN respectively.
