摘  要:山岭地区高速公路隧道施工难度大,易出现岩溶地带。在岩溶区进行隧道施工时,需加强超前地质预报工作,提前对掌子面前方的地层结构、性质、地下水分布情况进行充分了解,做到未雨绸缪,提前制订溶洞处理措施及突发情况应急预案。以南上庄隧道施工中的一次溶洞处理案例为基础,简述了施工中溶洞导致塌方情况的全过程处理方案,并阐明了隧道施工安全渡过溶洞的施工方法,以及岩溶地段隧道施工的注意事项。Highway tunnel construction in mountainous area is difficult and karst zone is easy to occur.When carrying out tunnel construction in karst area,it is necessary to strengthen geological prediction in advance,fully understand the formation structure,property and groundwater distribution in front of the face in advance,so as to prepare for rainy days,and formulate karst cave treatment measures and emergency plans in advance.Based on the treatment of a karst cave in the construction of Liuzhuang tunnel,this paper briefly describes the whole process treatment scheme of the cave-in caused by the karst cave in the construction,and expounds the construction method of the tunnel safely passing through the karst cave,as well as the matters needing attention in the tunnel construction in karst area.
