摘要
针对运营公路路基病害,采用地质调绘、地质钻探及钻孔深部位移监测等方法探明了路基的病害机理。根据路基病害特点,设计了圆形钻孔灌注桩+路基花管注浆+路面修复的处治措施。经监测表明,处治后的路基稳定性良好。
Based on the subgrade disease of an operating highway,using geological survey,geological drilling and deep displacement monitoring to obtain the mechanism of subgrade disease,then,according to the characteristics of subgrade disease,circular bored pile+subgrade perforated pipe grouting+pavement repair measures are designed.The result of monitoring shows that the subgrade stability after treatment is good.
