摘要
颍上县某项目取水口防洪影响处理工程采用压密注浆对穿坝管道周围土体进行防渗加固处理。为检测压密注浆防渗处理效果,采用高密度电法对注浆部位进行检测,并对地形起伏大的部位进行地形校正与不校正的对比分析。结果表明:注浆范围内的电阻率变化均衡,沿测线方向无明显异常,且在深度方向上的地层电性具有层状特性,注浆效果较好,经过地形校正的图像区域内电性反映更清晰,深度方向反映更准确。
In the flood control impact treatment project of an water intake project in Yingshang County,the soil around the dam-crossing pipeline is subject to anti-seepage and reinforcement treatment by compaction grouting.In the cause of detect the influence of compacting and grouting injection,the grouting part is tested by high-density electrical method,and the terrain correction and non-correction are compared according to the situation of the project site.The result surface:the resistivity changes uniformly in the grouting range,there is no obvious variation along the direction of the measurement line,and it has the electrical characteristics of the layered formation in the depth direction,the grouting effect is better,the electrical reflection in the image area after terrain correction is clearer,and the depth direction reflection is more accurate.
