| Abstract: | Following the excavation design and engineering geological conditions of the underground power station in the Longtan Project, the analog computations for the chamber group surrounding rock have been completed by using 2D elastic-plastic FEM. The excavating displacement and stress of the rock-mass, interaction among the caves are researched. Finally some suggestions for design and construction are put forward. |
