Stability Analysis of Surrounding Rock Mass of Underground Powerhouse Cavern

Abstract:

The underground powerhouse of Houziyan hydropower station has some typical characteristics such as high strata stress, large span and high sidewalls. In this paper, numerical simulation of continuous excavation and support of the underground caverns was performed using the Fast Lagrangian Analysis of Continuum method (FLAC^3D). Then, the distribution characteristic of the deformation field, stress field and plastic zones was analyzed based on the numerical calculation results. In addition, the distribution of stress was compared with microseismic events. It shows that stress concentration can cause micro-seismic events regional aggregation.
