Abstract:

The FLAC3D, which is a threedimensional explicit finitedifference software, is used to perform the numerical simulation in the underground caverns of Ertan Project in this paper. An interface model is established to simulate intermittent joint effect. The threedimensional seepage which has influence on the stability of the surrounding rock is calculated. Some conclusions are drawn, which can provide some useful reference for the study of largescale underground caverns.

Key words:  , joint seepage interface model systematic analysis stability of surrounding rock
