莲花台水电站坝基开挖后,揭露顺河断层F31,沿断层周边岩溶裂隙发育,断层底部及两侧多处涌水,对混凝土施工影响极大。且断层涌水具有零、散、远等特点,采取断层混凝土分段浇筑,分段处理涌水的措施。介绍了混凝土浇筑、不同涌水情况下的处理措施及灌浆补强处理措施。施工完成后透水率满足要求。 After the excavation of the dam foundation of Lianhuatai Hydropower Station, the Shunhe fault F31 is exposed. The development of karst fissures along the periphery of the fault and the influx of water at the bottom and sides of the fault have great impact on the concrete construction. The faulty gushing water has the characteristics of zero, scattered and far, and adopts the measures of segmented concrete pouring and subsea gushing treatment of gushing water. Introduced concrete pouring, different gushing water treatment measures and grouting reinforcement measures. After completion of the construction of water permeability to meet the requirements.
