水丰水电站坝址趾板建基面的处理分析

Analysis on the treatment of damsite toe slab foundation base in Shuifeng Hydropower Station

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。

Shuifeng Hydropower Station dam has high requirements on the stability and uniformity of damsite toe slab foundation base. However, the complex geological conditions of Shuifeng Hydropower Station cannot meet the requirements. In the paper, the effect of consolidation grouting operations in the problem processing of damsite toe slab foundation base in Shuifeng Hydropower Station is introduced, and acoustic detection method and borehole coring method are utilized for analyzing the treatment results. It is considered that consolidation grouting can be adopted for well solving various problems on damsite toe slab foundation base. And this paper provides reference basis for other projects.
