摘　　要：对万家口子碾压混凝土拱坝实际开挖揭露的断层软弱带分布情况进行了系统介绍,提出初步加固方案,通过计算分析其对大坝应力、变形及坝肩稳定等方面的影响,最终拟定安全可靠、经济合理的加固措施。初期蓄水期间的监测成果表明,大坝的应力大小及分布范围、坝肩变形、渗流量等指标均符合规范和设计要求,基础处理加固设计是合理的。The distribution of fault weak zone exposed by the actual excavation of W anjiakouzi RCC arch dam is systematically introduced,and the preliminary reinforcement scheme is proposed.Through calculation and analysis of its influence on dam stress,deformation and stability of dam abutment,the safe,reliable,economic and reasonable reinforcement measures are finally formulated.The monitoring results during the initial impoundment show that the stress value and distribution range of the dam,the deformation of the dam abutment and the seepage flow are in line with the specifications and design requirements,and the foundation treatment and reinforcement design is reasonable.
