摘　　要：注浆效果的优劣直接影响着施工的质量进而影响着工程项目的整体安全和效能,对注浆效果进行检测具有重要意义。但是由于注浆施工区域特有的隐伏性,注浆效果难以轻易检测或者评价效果不佳无法为施工提供可靠的参考。以头石山尾矿库排洪隧道脱空注浆加固施工为例,分析了高密度电法的工作原理,布置方式及操作流程,介绍了使用高密度电法对一期注浆效果进行检测分析,取得了良好的应用效果。结果表明:高密度电法能快速、有效的在较大范围内对隧道注浆效果进行检测,把关施工质量,为后续施工提供参考。The quality of the grouting effect directly affects the quality of construction and the overall safety and efficiency of the project,so it is of great significance to detect the grouting effect.However,due to the unique concealment of the grouting construction area,the grouting effect is difficult to be easily detected or the evaluation effect is not good,which cannot provide a reliable reference for the construction.In this paper,the working principle,layout,and operation process of the high-density electric method are analyzed by taking the construction of the drainage tunnel of Toushishan tailings pond as an example,and the effect of phase grouting is detected and analyzed by high-density electric method,which has achieved good application effect.The results show that the high-density electric method can quickly and effectively detect the effect of tunnel grouting in a large range,check the construction quality,and provide a reference for the subsequent construction.
