摘要
溶洞坍塌之后造成的地表变形和移动对路基的稳定性影响较大,必须对溶洞进行工程处理。本文针对嘉宁公路K21+590段岩溶具体情况,采用数值计算方法,对所提出的工程处理方法的适应性进行了论证。计算分析结果表明,所提溶洞综合处理方法可行。
Devastating effects on the road embankment stability and deformation were concerned because of the karster cave collapse resulting in obvious ground deformation. The treatment method should be adapted for likely collapsing caves. According to the actual collapse situation of K21 ＋590 in Jia-ning road, the treatment method for likely collapsing caves were judged by FLAC3D numerical simulation. The numerical simulation analysis showed that the treatment method were reliable.
