摘　　要：岳圩口岸联线公路位于喀斯特地貌分布区,沿线岩溶发育,地质条件复杂。对于岳圩2号隧道进口左洞ZK7+515.5~ZK7+534隧底溶洞发育,设计单位给出了采用桩筏结构进行溶洞跨越的处治方式,但考虑到工期、成本等因素,通过进一步地质勘探,在充分了解地质情况的前提下,对施工方案进行优化、调整。后经认真组织施工,顺利、安全地完成了溶洞跨越施工,既保证了工期及质量,又取得了良好的效益,为今后同类型工程进洞施工积累经验。Yuexu port joint highway is located in the karst landform distribution area,with its karst development and complex geological conditions.For the development of tunnel bottom cave in left cave ZK7+515.5~ZK7+534 at the entrance of Yuexu No.2 tunnel,the design unit proposes the way of using piled raft structure to cross the karst cave.However,considering the factors such as construction period and cost,the construction scheme is optimized and adjusted through further geological exploration on the premise of fully understanding the geological conditions.After careful organization of construction,the construction crossing the karst cave is completed successfully and safely,which not only ensures the construction period and quality,but also achieves good benefits,accumulating experience for the entering cave construction in the same type of projects in the future.
