山口水电站工程混凝土重力坝坝基灌浆处理

Concrete gravity dam foundation grouting of Shankou Hydropower Station

结合山口水电站工程混凝土重力坝坝基工程地质条件,介绍了坝基开挖、断层处理要点,以及坝基固结灌浆、帷幕灌浆的技术要求和施工工艺。对投运后大坝各项监测数据进行分析,结果均在正常范围之内,大坝运行正常,证明坝基处理方法得当,效果好。

Combined with analysis of engineering geological conditions, an introduction was made on the construction of concrete gravity dam foundation of Shankou Hydropower Station, including foundation excavation, treat- ment of fault, technical requirements and construction technique of foundation consolidation grouting and curtain grouting. All monitoring records of main dam since it was put into operation are all within normal range, demonstrat- ing that treatment measures for dam foundatinn rt^ndt^r~ cr.nrl ,~ff,=o~
