一、概述在进行混凝土重力坝或支墩坝等水工建筑物设计时,各国现行规范都规定必须审查抗滑稳定,其中决定抗滑稳定性的一个关键首先是确定坝基断裂路线及其参数。关于这个问题,到目前为止,除注意了坝基内存在危弱结构面之外,皆指混凝土与基岩胶结面为断裂(破坏)路线。其抗剪强度参数的选择将依据混凝土与基岩抗剪强度试验资料来选定。一般试件剪切面积为50×50平方厘米,最大水平力与剪切面方向的夹角为15°,
I. Overview In the design of hydraulic structures such as concrete gravity dams or supporting dams, current national codes stipulate that the stability of anti-skidding must be examined. One of the key points in determining the stability of anti-skidding is to determine the fault line and its parameters. So far, except for noticing the existence of the weak structural surface in the dam foundation, all of them refer to the fracture surface of the concrete and the base rock cemented surface. The choice of shear strength parameters will be based on concrete and bedrock shear strength test data to select. General specimen shear area of 50 × 50 square centimeters, the maximum horizontal force and the angle between the direction of the shear plane is 15 °,
