电测深法岩溶路基注浆质量检测模型试验研究
A study of the quality test model of resistivity sounding for detecting grouting effect of karst roadbed
摘要
Abstract
Due to the difficulty of quality test of karst roadbed, based on typical field geological sections, a model of stenopeic limestone is established, and analysis of the results of resistivity sounding test on many sections before and after grouting is carried out, and comparison with the real diffusion area in the model is also performed. The results suggest that after the cement flow is injected into the model, the apparent resistivity decrease more obviously than before grouting. When the decreased extent is equal to or above 15% after grouting, the grouting effect is good and the rational test time is 7 days after grouting. The field tests basically verify the results of the model tests. However, the field tests are significantly controlled by ground water level. As a result, the partial faults of the judgment may be caused.关键词
