摘　　要：通过地表调查、点荷载试验、声波测试、结构面网络模拟(Monte-Carlo)等综合手段,对鱼简河水库RCC抛物线双曲拱坝坝址坝基岩体进行分类和评价,提出了本工程大坝建基面可以抬高2 m的合理化建议;采用有限元法对位于坝肩中下部的软弱夹层进行处理前后的对比分析,经研究认为必须采用深挖混凝土置换、深孔固结灌浆等综合处理措施,才能保证大坝的安全运行。The dam of Yujianhe Reservoir is a RCC parabola double curve arch one. Through some means such as surface investigation, test of point load,, survey by sound wave, Monte-carlo simulation of structural plane and etc. on the base of classifying and appreciating the foundation rock of the dam site, the suggestion, that foundation plane for building dam could rise to 2 m, was be presented. But calculation research makes know that some soft strata located on the middle or down side of abutment must be treated by effective measures in order to ensure safe operation of the dam.
