基岩缓倾角软弱夹层的处理是混凝土坝设计中至今没有很好解决的问题,重力坝和拱坝规范编制时采取回避态度。本文根据上犹江、桓仁、德沃夏克、葠窝、柯依那、白山、双牌、葛洲坝伊泰普等工程实例,对软弱夹层的力学性能及其测定、坝基夹层计算,坝基渗流及夹层处理等问题,提出个人的看法和建议、抛砖引玉,希望能促进问题的解决。 The treatment of bedrock gentle dip and weak interbed is a problem that has not been solved so far in the design of concrete dams. The attitude of gravity dam and arch dam should be avoided when they are compiled. Based on the engineering examples of Shangyoujiang, Huanren, Dvorak, Shenwo, Keyi Na, Baishan, Shuangpai and Gezhouba Itaipu, the mechanical properties and determination of soft interlayer, the calculation of dam foundation, And mezzanine treatment and other issues, put forward personal views and suggestions, initiate, hoping to promote the solution of the problem.
