摘要
在岩溶发育地区修建公路,岩溶病害是工程建设亟待解决的问题。目前路基下伏溶洞稳定性分析还比较少,溶洞的治理措施没有形成统一的标准,总结国内外常用的岩溶勘察技术,并分析各类技术的适用条件与范围,阐明封闭型与敞开型溶洞的失稳机理,归纳溶洞稳定半定量分析方法,依托项目详细介绍注浆、跨越、强夯等岩溶路基处治措施,为类似工程提供参考。
This paper summarized the domestic and foreign common karst exploration technology and analyzed the application conditions and scope of various types of technology. It also illustrated the instability mechanism of the closed and open type karst cave, analyzed the cave stability semi-quantitative analysis method.Based on the project,it introduced the grouting, span,dynamic compaction and other karst roadbed treatment measures,which provided a reference for similar engineering.
