Scope of problem from this study is the dynamic load used for slope stability analysis is the effect of blasting activities and the prediction of vibration from trial blasting in Tunnel #11-1. Meanwhile, the slopes of Bohong Mountain were analyzed in 2D using the finite element method. The data will be processed using RS2 to determine the value of safety factor and permanent displacement that occurs on the slopes as a effect of blasting in Tunnel #11. The analysis used to determine the value of safety factor is pseudostatic analysis and to determine the value of permanent displacement, dynamic loads used is the blasting load.
Penerapan Karya Tulis
Excavation for Tunnel # 11 of the Jakarta - Bandung High-Speed Railway using mechanical excavation methods for relatively weak rocks (Silty Clay and Gravelly Clay) and blasting methods for relatively hard rocks (Breccias and Andesites). The vibrations arising from this detonation will affect the environment. This study aims to determine the effect of blasting in Tunnel #11 to the stability of the slopes in the residential areas.
