摘　　要：岩溶发育区公路隧道建设过程中往往会遭遇形态各异的溶洞,对隧道施工和运营安全产生不利影响。以利万高速公路齐岳山隧道揭露的大型溶洞为案例,综合考虑空间关系、岩体稳定性、地下水和基础承载力等影响因素,对大型溶洞处治技术进行了研究总结,所得结论可供类似工程设计和施工参考。During the construction of highway tunnel at karst areas,karst caves with different forms are often encountered,which have negative influence on tunnel construction and operation safety.Taking the large karst cave exposed in Qiyueshan Tunnel of Liwan Highway as the example,and comprehensively considering the influence factors such as spatial relationship,rock mass stability,groundwater and foundation bearing capacity,the treatment technology of large karst cave was studied and summarized,which can be used as a reference for similar engineering design and construction.
