There are many factors to affect the wall-rock 's stability of underground powerhouse, and the structure character of rock mass is one of the factors. So, the structure character study of rock mass is very useful to value the wall-rock's stability of underground powerhouse. This article, by surveying data of one underground powerhouse of hydroelectric station, introduces how to analyze survey data by using statistical ways and means and find the structure character of rock mass at last. That will offer reliable basic-data for studying wall-rock's stability of underground powerhouse
