MONITORING ANALYSIS OF ROCK STABILITY OF UNDERGROUND MAIN POWERHOUSE IN XIANGJIABA HYDROPOWER STATION

Zhu Zhao-hui

Open publisher page 2 citations

Abstract

It describes the anchoring effect and surrounding rock deformation monitoring during the excavation process of the underground powerhouse on the right bank of Xiangjiaba hydropower station.The monitoring results show that:due to better control of the excavation and support,the overall deformation of surrounding rock is little,and through analyzing the deformation monitoring data in entire process of excavation,the sphere of influence of excavation on surrounding rock and the estimation about deformation monitoring of pre-loss are obtained.This example is available for reference to similar projects.
