Sensitivity Analysis of Joints' effects on Damage Zones in Surrounding Rockmass

摘要

This present paper, taking a large-scale underwater power station in China as background engineering works, carries out sensitivity analyses of various parameters of jointed rockmass on the scope of damage zones in the rockmass surrounding the works. It gives major sensitivity parameters and discusses the trend and possibility of these parameters' effect on the damage zone of surrounding rocks as well as makes some suggestions on the exploration and construction.
