摘要
为了弄清318国道野三关某段公路路基下溶洞的分布情况,采用地质雷达圈定了溶洞的分布范围。经过对溶洞扰动区的稳定性分析,选择注浆法对其加固处理,在溶洞加固之后进行了复测,效果显著。
In order to make clear the karst cave distribution beneath roadbed at Yesanguan section of 318 national highway,GPR was used for delineating.By the analysis on the stability of the karst disturbed zone,the jet grouting method was chosen for the reinforcement.The strengthening region was detected again,and the effect is very significant.
