超高密度电法在工程病害治理勘察中的应用

为验证超高密度电法在工程病害检测中的效果及可靠性,基于铁路路基沉陷和坝体渗漏病害工程检测案例,对整治前后分别进行现场检测,并对检测结果进行对比分析.研究表明:在工程病害检测中,超高密度电法能够快速准确地查出病害位置,测试段反演图像可清晰反映缺陷断面异常形态.测试段整治后,电测剖面整体视电阻率均较低,高阻异常消失,反映出...

Application of Ultra-high Density Electric Method in Engineering Disease Governance Prospecting

Subgrade subsidence and dam seepage are common diseases in railway and water conservancy projects.In order not to affect the operation of railway and other projects,this paper explores the detection effect and reliability of ultra-high density electrical method in the geological investigation of engineering diseases.Through the application of ultra-high density electrical method in terms of subgrade subsidence and dam seepage,on-site disease detection was carried out at the same time.The detection and comparative analysis were carried out for the damaged section and the treated section.The test results show that the ultrahigh density electrical method can quickly and accurately investigate and deal with the disease causes in the engineering disease detection.Through the inversion image display of the test section,the abnormal shape of the subgrade section is clear,which provides a reliable basis for the later disease treatment.This method is time-saving and economical for finding out the causes of the engineering diseases.
