Based on the mechanism of shear - slipping dam collapse , the state function of high arch dam shear - slipping failure mode is established , and the function involves four non - fully - independent random variables , namely , compressive stress , shearing stress , coefficient of friction and coefficient of cohesion , and is of nonlinear characteristics 根據剪滑潰壩機理建立了高拱壩剪滑失效模式的狀態函數,該狀態函數包含壓應力、切應力、摩擦系數以及粘結力系數等4個非完全獨立的隨機變量,且具有非線性特征。
