摘要
在水利工程堤坝除险加固技术中防渗墙工程具有隐蔽性,要保证其施工质量,发挥其应有的工程质量效果,检测防渗墙的质量就显得尤为必要。利用高密度电阻率法研究防渗墙物理模型,通过注水实验来进行人工模拟,将背景电阻率值与注水后的电阻率值进行对比,结果显示缺陷反应与实验模型的缺陷具有良好的对应关系,说明高密度电阻率法对防渗墙缺陷的检测具有良好反映能力。所得结果可以为防渗墙无损检测中选用高密度电阻率法作为检测方法提供参考。
In the reinforcement technology of hydraulic engineering dams, the anti-seepage wall engineering has concealment.It is necessary to ensure the construction quality and exert its due quality effect. It is especially necessary to test the quality of the anti-seepage wall. In this paper, the high-density resistivity method is used to study the physical model of the seepage wall. The water injection experiment is used to simulate the background, and the background resistivity value is compared with the resistivity value after water injection, the results show that the defect reaction has a good correspondence with the defects of the experimental model, indicating that the high-density resistivity method has a good ability to reflect the defect of the anti-seepage wall. The obtained results can be used as a reference for the high-density resistivity method in the nondestructive testing of cut-off walls.
