摘　　要：大藤峡水利枢纽工程坝基软硬岩互层及交错变化复杂,且泄水闸闸门推力较大,为保证工程安全性,对其稳定性水平进行分析与研究。以三维裂隙网络为基础,获取了坝基岩体内部裂隙的连通率和岩体等效力学参数,然后采取数值模拟(离散单元法)的方法对泄水闸28号坝段基础的稳定性模拟与分析。分析结果表明闸坝与坝基整体稳定较好,符合安全需求。The dam foundation of the Datengxia water conservancy project is interbedded with soft and hard rocks with complex staggered changes,and the sluice thrust of the sluice gate is relatively large.In order to ensure the safety of the project,its stability is studied.Based on the three-dimensional fracture network,the connectivity and equivalent mechanical parameters of fractures in dam bedrock were obtained,and then the stability of dam foundation of sluice 28#was simulated and analyzed by numerical simulation(discrete element method).The analysis results showed that the overall stability of sluice and dam foundation is good and meets the safety requirements.
