水口电站明渠导墙碾压混凝土抗剪强度特性试验研究

Study on Shear Resistivity Test of RCC Channel Guide Wall in Shuikou Hydropower Station

碾压混凝土坝体中存在着众多的水平层面，而层面的各种物理力学性质比碾压混凝土本身差，在结构应力、温度应力作用下，对坝体的抗滑稳定、整体性及防渗性均可能产生不利影响。对水口电站明渠导墙不同层面碾压混凝土进行的变形性能和抗剪强度试验研究，取得了较丰富的现场资料，得到了一些感性认识。

There are many horizontal layer surfaces in RCC dam body. The physical and mechanical properties of the surface are poorer than those of the layers. By the force of structural stress and thermal stress, they may produce negative effects on stability, slide-resistance, and seepage prevention. A wealthy of in-situ data are obtained through testing deformability and shear resistance of different RCC layer surfaces of channel guide wall in Shuikou Hydropower Station. Some experience is accumulated.
