Abstract：As one of the main support unit in underground engineering, bolt is important to underground engineering stability. In addition,it is of great porion of underground engineering investment. Therefore, reasonable bolt support scheme is of great importance to both safety and economy of underground engineering. In this paper, by using finite element method,three bolt support schemes are designedto simulate the excavation of an underground hydropower house. An equivalent model is used in the analysis to simulate mechanical effect of bolt. Thecomparison ofnumerical results with diferent bolt support schemes is given.
