摘　　要：为掌握水利水电工程中深水截流堤头坍塌机理与稳定性规律、全面评价大江大河截流难度,在工程界已采用理论分析、数值计算及物理模型试验等方法取得相应成果的基础上研究了采用临界与稳定坡度理论,建立了坍塌及稳定性模型,结合三峡工程大江深水截流进行了数值计算求解,实际应用中取得了良好的预测与控制效果,由此给出了对大江大河截流难度的新认识。In order to master the slump mechanism and the stability of deep-water dyke of the hydropower projects and to comprehensibly appraise the difficulty of large river closure, based on the results gotten by the theory analysis, the numerical calculation and the physical model test, this study built the slump and stability model. By using the utilization of the critical and stability slope theory, and found the solution by the numerical calculation in combination with the deepwater closure of the Three Gorges project. This study result gains good forecast and control effectiveness and gives the new knowledge on the difficulty of large river closure.
