水丰水电站大坝对坝址趾板建基面的稳定性、均一性有着很高的要求,但是水丰水电站所处的复杂地质条件无法满足该要求。本文介绍了固结灌浆作业在水丰水电站中坝址趾板建基面问题处理中的作用,并利用声波检测、钻孔取芯手段对处理结果进行了分析,认为固结灌浆可以很好地解决坝址趾板建基面出现的种种问题,为其他工程提供了参考依据。
The dam of Shuofeng Hydropower Station has high requirements on the stability and uniformity of the foundation of the toe slab at dam site, but the complicated geological conditions of Shuifeng Hydropower Station can not meet the requirements. This paper introduces the role of consolidation grouting in the treatment of dam toe slab foundation in Shuofeng Hydropower Station, and analyzes the treatment results by using acoustic detection and core drilling. It is concluded that consolidation grouting can well The problems of the emergence of plinth construction in dam site are solved, which provide references for other projects.
