Abstract：Using Three-Dimensional Fast Lagrangian Analysis of Continua (FLAC3D) method，the excavation and the effect of support are simulated for underground power-house of langyashan pumped-storage power station. For the 1# unit profile with representative geological condition and 2# unit profile with comparatively complicated geological condition，the characters of stress，displacement vector and plastic zone of surrounding rock masses after excavation are analyzed. Some useful conclusions are gained. It will be significant for the construction of the project.
