摘要
几内亚苏阿皮蒂水利枢纽项目坝基中间5号~43号坝段为辉绿岩,左右岸其他坝段为砂岩、泥质粉砂岩。为减少坝基和绕坝肩渗漏,防止渗漏水流对坝基及两岸边坡稳定产生不利影响,坝基进行了帷幕灌浆防渗。为全面检测帷幕灌浆的质量,结合国内灌浆规范及法国咨询工程师的要求,采用压水试验、压浆试验、孔内成像等方式进行检测,判断帷幕灌浆质量是否满足设计要求。
The rock in the dam foundation of No.5-43 dam sections in Souapiti Hydro Project is diabase,and the rocks in the other dam sections are sandstone and silty siltstone.In order to reduce the seepage of dam foundation and around the abutment of dam,the curtain grouting is carried out to prevent the adverse effect of seepage flow on the stability of dam foundation and slopes.In order to comprehensively detect the quality of curtain grouting,combined with the requirements of domestic grouting codes and French consulting engineers,the water pressure test,grouting test and in-hole imaging are adopted to check the quality of curtain grouting to determine whether the curtain grouting quality meets the design requirements.
