摘　　要：针对三岔河水库坝址区地形地质条件较复杂,断层、岩体节理裂隙发育、表层强烈溶蚀风化和裂隙性岩溶风化等,存在裂隙型绕渗、岩体完整性差及边坡稳定性差等问题。从地形地貌、地层岩性、地质构造、物理地质现象和岩溶水文地质条件等方面,对坝址区工程地质条件进行详细勘探和测绘分析,并优选地形地貌条件较优、地质条件适应性强的上坝址混凝土重力坝方案。工程地质问题的详细论证分析,为水库枢纽布置及坝基、坝肩和两岸防渗加固处理提供了详细地质资料及结论。Aiming at the complex conditions of topography and geological,faults,development of rock joints and fractures,strong karst weathering on the surface,and weathering of cracked karsts which will cause the problems of fracture type infiltration,poor rock integrity,and poor slope stability in Sanchahe reservoir. The geological conditions of the dam site has been explored and mapped in detail based on the topography,formation lithology,geological structure,physical and geological phenomena,and karst hydro-geological conditions. The upper dam site preferred concrete gravity dam scheme with excellent terrain and geological conditions and strong adaptability of geological conditions also been adapted. The detailed argument and analysis of engineering geology can provide detailed geological data and conclusions for the layout of reservoir hub and anti-seepage treatment for the foundation abutment and two banks.
