Abstract

Underground engineering has broad prospects for development, but its surrounding rock stability is related to the project construction security as well as operation security. In this paper, quasi-static method is adopted, and based on the surge chamber at the Liuping Hydropower Station, the overall three-dimensional model is established to analyze the surrounding rock stability of surge chamber in complex geological areas under seismic conditions. The compute results show that the overall stability of the surge chamber surrounding rock and the lining structure is good, but the safety factor near the left side wall and right spandrel is small. So, it is necessary to take the key reinforcement measure and pay the key attention in the construction.
