摘要： 亭子口水利枢纽工程坝址区位于红层沉积岩体内,存在较多的各类结构面。通过对21组各类结构面进行原位直剪试验,揭示了各结构面的抗剪强度特性。同时通过算术平均值以及图解2种方法对各类结构面抗剪强度参数分别进行统计,所得到的统计成果总体相近。成果除可供本工程设计取值外,对于其它类似工程也具有较好的参考价值。

关键词: 亭子口电站, 结构面, 抗剪强度, 直剪试验

Abstract: The dam site of Tingzikou Power Station is located in red bed sedimentary rocks area,and there are many structural planes in this area. Through in-situ direct shear tests on 21 sets of typical structural planes,the shear strength properties of the structural planes were revealed. Furthermore,statistics of the shear strength parameters were obtained by means of arithmetic mean value and diagram. The statistical results by the two methods are similar in general. The research findings not only serve as the basis for the design of this project,but also could be taken as reference for other similar projects.

Key words: Tingzikou power station, structural plane, shear strength, direct shear tests
