| 摘 要： | 工程岩体的强度由于受到岩性、节理、地下水、温度场等的影响导致其强度的确定成为岩石力学界的一个重大难题。工程岩体具有地质、力学和工程3大特色，其强度的确定也应综合考虑这3种因素。在此基础上，提出利用经验类比、岩体质量评分体系和连通率的方法结合宏观地质条件判断结果综合确定工程岩体强度的方法——GMEM(geology，mechanics and engineering memod)。运用该方法在向家坝等许多工程中得到很好的应用。

| Abstract: | 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.. |
