新桥隧道填充式溶洞处治方案研究

Research on the Treatment Scheme for Filling-type Karst Caves in Xinqiao Tunnel

以新桥隧道填充式溶洞处治方案为研究案例,分析工程现场地质情况,根据溶洞分布特征,通过方案比选,制定了有针对性的处治方案。文章采用的软基处理方案已在项目中成功应用,研究结果可为类似工程案例提供参考。

Taking the research on the treatment scheme for the filling-type karst caves in Xinqiao tunnel as an example,the geological conditions of the engineering site are analyzed.Based on the distribution characteristics of karst caves,through the scheme comparison and selection,the targeted treatment scheme is formulated.The soft foundation treatment scheme adopted in the article is successfully applied in the project,and the research results can provide reference for similar engineering cases.
