RESEARCH OF A SYNTHETICAL METHOD GMEM ON ASCERTAINING SHEAR STRENGTH FOR ENGINEERING ROCK MASS
工程岩体抗剪强度确定综合方法——GMEM研究

The determination of the strength for engineering rock mass is one of the most important problems in rock mechanics because it is influence on lithology,joint,undergroundwater and temperature field and etc.. This paper considers that the engineering rock mass has the characters of geology,mechanics and engineering,and the above-mentioned three factors should be considered for the determination of strength synthetically. At the same time,this paper puts forward the geology,mechanics and engineering method(GMEM) to ascertain the strength of engineering rock mass that combins experience analogy,grading system of rock mass quality,and connectivity ratio method with estimation of macroscopical geological condition. The GMEM has been applied in many projects,such as the Xiangjiaba hydropower station and etc..
