Rock slope stability assessment using kinematic analysis at Gunung Batu, Lembang, West Java, Indonesia

Abstract

Abstract Discontinuity plane in the Gunung Batu area associated with the geological structure of the activity of the Lembang fault has the potential to induce rock slope failure hazard to the surrounding residential areas. A series of slope stability analyses of the Gunung Batu was carried out using rock mass rating and kinematics analysis to assess the rock slope stability in the Gunung Batu and determine the rock failure type. According to the results of the rock mass rating, the outcrop of Gunung Batu is classified as a good rock. Meanwhile, kinematic analysis from three joint sets shows that the rock failure type is characterized by wedge and toppling failures. However, the analysis results of the Slope Mass Rating (SMR) indicate that the rock slope stability in Gunung Batu is considered in partially stable to stable condition.
