摘要
通过透水率检测标准试验检测岩溶路基注浆效果,具体采用模型试验方法,并在理论分析的基础上,研究透水率检测标准应用时存在的基础问题。研究发现,覆盖型潜蚀塌陷的控制因素——临界裂隙开度主要受到覆盖层临界水力梯度、密实度和土质等的影响,并最终确定岩溶路基注浆效果透水率检测定量标准选取潜蚀塌陷临界透水率值47Lu。
In this case, the permeable rate of detection standard test, detection of Karst Subgrade grouting effect, the specific use of model test method, and the theoretical analysis based on, the pervious studies rate detection criterion is based.The study found that--critical fracture is mainly covered layer critical hydraulic gradient, density and soil texture, and ultimately determine the Karst Subgrade grouting effect of permeable rate detected by quantitative standard selected suffosion collapse critical permeability rate 47Lu suffosion type collapse control factors covering.
