高密度电法在云桂铁路路基岩溶注浆检测的应用

摘要

针对传统铁路路基岩溶注浆检测方法的偶然性和局限性，结合云桂铁路珠琳段岩溶注浆检测，分析高密度电法工作原理及流程，通过研究注浆前后视电阻率变化对注浆效果进行判断，并采用质量自检孔方法验证，结果表明：高密度电法能够全面、客观、快速可靠地检测路基岩溶注浆效果。%In view of the contingency and limitations of traditional detection methods for karst grouting of railway subgrade, this paper dissects the grouting inspection of Zhu-lin section of Yun-gui railway, analyzes the working principle and process of high density resistivity, accesses the effect of grouting through the change of apparent resistivity before and after grouting and verifies it with self-test holes. The results show that the high density resistivity is a comprehensive, objective and reliable way to test the effect of karst grouting in railway subgrade.
