摘　　要：根据大量地质工作,我们在隔河岩枢纽坝区建立了岩溶化河间地块存在非岩溶岩块的论点,并作出无岩溶管道渗漏的结论。对水库中上段滑坡集中分布的地区布置了周密的监测网。坝基地层为岩溶化程度很高的寒武系石龙洞灰岩,顺河断裂发育,并有多条剪切带,两岸还发育有多个岩溶通道系统,因而对坝基岩体、洞室和边坡稳定以及帷幕工程有重要影响。通过工作,对上述问题作了分析和预报,并提出了相应的处理建议。Based on nomorous geologic works, a new concept on non-carst rockmass exist in carst rockmass area without piping leakage has been developed. A monitoring network for some major and unstable landslids has been established. The foundation at damsite has high degree carst rockmass, developed faults and fractures as well as carst rock access at both banks. So it must affect the foundation, opening and slope stablity as well as curtain. This paper indicates the boundary condition of geologic model with control of foundation stablity, the route and minimum limitation of anti-seepage curtain, a forecast for leakage in the openings treatment proposals for the nature openings and slopes in outlet.
