Analysis of slope stability by using Oasys Slope version 18.1 software

Guan Khim Chew

Abstract

A fill slope with two different angles and fill slope by extend the toe of the fill slope were proposed to stabilize the permanent fill slope at KM 47.9 of Tamparuli -Ranau Highway, Sabah. In this study, software Oasys Slope version 18.1 was used to analysis the possibility failure of the existing fill slope. Bishop Method with Variably Indined Interslice Forces was used for the analysis. Two method of proposed fill slope were analyzed. The result showed that the factor of safety fur the existing slopes close to factor of safety 1. The existing slopes tend to fail. For the proposed slope, the factor of safety increased after application of the proposed fill slope.
