An integrated study on slope stability has been conducted in the high weathering zone of the tropical and active tectonic country, Indonesia. The research aims to introduce an integrated and comprehensive approach in studying the soil and rock slope stability. Geophysical methods, including two seismic refraction tomography (SRT) and electrical resistivity tomography (ERT) lines, were deployed to determine the slip zone of the landslide. Slope kinematic analysis and rock mass classification were performed on the slope surface for obtaining data of engineering geology combined with Standard Penetration Test (SPT) data collected next to the sloping road. The soil slope stability analysis was simulated by employing the Slope/W software to determine the factor of safety. The geophysical methods revealed three layers of rock and soil on top of the rock layer, showing the slip zone of the landslide. The kinematic analysis revealed the planar failure, which possibly occurred in Site B of Babarot—Gayo Lues road in Aceh Province due to the parallelism between slope and joint. The integrated data from the geophysical methods and in situ RMR indicate that the rock mass classification in sub-surface is classified as Very Good and Good Rock. It appears to be stable. The soil above the slope in sites A and B has 1.058 and 1.182 factor of safety, respectively; yet, it has less than 0.847, the factor of safety, when loaded by the earthquake and it is unstable.

在热带和活跃构造国家印度尼西亚的高风化带进行了边坡稳定性的综合研究。该研究旨在引入一种综合和综合的方法来研究土壤和岩石边坡的稳定性。部署了包括两种地震折射层析成像（SRT）和电阻率层析成像（ERT）线在内的地球物理方法来确定滑坡的滑动带。在斜坡上进行了斜坡运动学分析和岩体分类，以获取工程地质数据，并结合在斜坡附近收集的标准渗透试验（SPT）数据。通过使用Slope / W软件来模拟土壤边坡稳定性分析，以确定安全系数。地球物理方法揭示了岩石层顶部的三层岩石和土壤，显示了滑坡的滑移带。运动学分析表明，平面破坏可能是亚齐省的巴巴罗特-加约·雷斯路段的B站点发生，原因是坡度和节点之间的平行度。来自地球物理方法和原位RMR的综合数据表明，地下岩体的分类分为非常好和好岩石。它似乎是稳定的。A点和B点斜坡上方的土壤的安全系数分别为1.058和1.182。但是，在地震作用下它的安全系数小于0.847，并且不稳定。由于边坡与节理之间的平行性，这很可能发生在亚齐省的巴巴罗特-加约雷斯路B站点。来自地球物理方法和原位RMR的综合数据表明，地下岩体的分类分为非常好和好岩石。它似乎是稳定的。A点和B点斜坡上方的土壤的安全系数分别为1.058和1.182。但是，在地震作用下它的安全系数小于0.847，并且不稳定。由于边坡与节理之间的平行性，这很可能发生在亚齐省的巴巴罗特-加约雷斯路B站点。来自地球物理方法和原位RMR的综合数据表明，地下岩体的分类分为非常好和好岩石。它似乎是稳定的。A点和B点斜坡上方的土壤的安全系数分别为1.058和1.182。但是，在地震作用下它的安全系数小于0.847，并且不稳定。
