某水库工程防渗墙质量检测与评价

Inspection and Evaluation of Water-Proof Wall in a Certain Reservoir

某水库工程防渗墙检测在运用综合物探方法(包括高密度地震影像法、探地雷达法、高密度电阻率法)进行普测的基础上,又利用防渗墙的骑缝孔进行了跨孔超声波检测,同时对部分墙体进行压水试验以检验防渗效果。通过对检测结果的综合分析,指出了可能存在裂缝、空洞或夹泥的具体位置,对防渗墙的整体防渗效果作出了评价。

In a certain reservoir, we use comprehensive methods to inspect and evaluate the water-proof wall. These methods include： generating high-density seismic graph, GPR, and analyzing high-density resistivity methods. Additionally, quality of concrete wall, also has been inspected in supersonic wave by the splitting-gas; at the same time, we test the water-proof effect of part of the wall by exerting appropriate water-pressure. Through comprehensive analysis of the test results, we point out the specific place of possible deficiency and make final evaluation of the overall water-proof effect of the wall.
