Study on Stability and Anchoring Effect of Jointed Rock Mass of An Underground Powerhouse

Li, S.C. / Chen, Wei Zhong / Zhu, Wei Shen / Qiu, X.B. / Yang, Chien Hsin

This present paper adopts a constitutive model for elastic damage of intermittently jointed rock mass, damage-evolution equations and a supporting model of damaged rock-bolt bar(DRBB) element to simulate effect of reinforcement. The results have indicated that the above method well describes the progressive failure process of the surrounding rock mass and the anchorage effect. The theoretical achievements are of referential value to designers.
