摘要
针对山岭重丘区不良地质隧道施工问题,以新圆梁山隧道2号高压富水溶洞段隧道为工程背景,研究在岩溶地段发育有高压富水充填溶洞等地质条件下,溶洞段隧道超前预支护以及隧道扩挖施工方法的比选,通过对现场监控量测数据对比分析验证了施工方法的可行性。
In view of the construction problems of tunnels with unfavorable geological conditions in mountainous and hilly areas,taking xinyuanliangshan tunnel high pressure water rich karst cave section tunnel as the engineering background,this paper studies the comparison and selection of advance pre support and tunnel expansion construction methods in karst section under the geological conditions of high pressure and rich water filling karst cave in karst area,and verifies the construction method by comparing and analyzing the field monitoring data.
