Abstract The underground powerhouses′ rock masses at Xiluodu hydropower station are discontinuous and anisotropic damage influenced by the inner beddings of the basalt. The elasto-plastic damage theory is used to analyze the stability of surrounding rock. A good construction organization and technological are executed to control the rock excavation damage in order to ensure the rock beam forming. Moreover，the safety monitoring feedback is implemented for the location of geological defects，and the monitoring results are used to estimate the surrounding rock stability. Through reviewing the rock mass engineering practice process of a typical underground powerhouse such as the complex geological conditions，stability analysis，excavation and support procedures，and safety monitoring analysis，a number of insights for the design concept and implementation of the project are put forward，which can provide direct reference for the giant underground powerhouse engineering.

Key words： rock mechanics underground powerhouse stability of surrounding rock Xiluodu hydropower station
