摘　　要：软弱层带强度参数是水电工程设计中十分重要的参数,对建筑物稳定、边坡稳定的评价和宏观把握以及加固处理工程量具有重要意义.但是,目前国内外对该参数的研究进展不大,没有任何一种方法被公认可以合理、可靠地获取该参数,只能通过尽可能多的试验去获得一系列的试验数据,掌握试验过程情况,再通过整理分析这些数据,找出参数变化的规律性、趋势性.通过分析各试验的成果,在对地质环境、结构面物理力学性状总体把握的基础上,给出工程区各类软弱结构面的力学参数.以黄河上游某水电站Ⅱ号变形体控制性底滑面为工程实例,分析由各试验方法得到的成果,并给出该强度参数较为合理的建议值.该论证选取方法可供同类工程借鉴.The strength parameters of the weak layers are some very important parameters for the hydropower engineering design. It is very important for the assessment and macroscopic grasp of building stability and slope stability,and the size of project amount of strengthening treatment. But,at present the research of this parameter is less,and no single method is recognized reasonable and reliable access to the parameters. And only through as much as possible tests,a series of experimental data are obtained to master the testing process case,and then by analyzing and sorting these data,the parameters regularity and trend are identified. By analyzing the results of each test,on the basis of the overall grasp of the geological environment and the physical and mechanical traits of structure surface,the mechanical parameters of various types of weak structure plane in the project area are given. Taking the bottom sliding surface of deformable body Ⅱ of a hydroelectric power station on the upper reaches of the Yellow River as an engineering example,the results obtained by each test method are analyzed,respectively and a reasonable recommendation values of the intensity parameters are given,and the demonstration selection method is available for similar projects.
