摘　　要：随着我国铁路建设的加速,岩溶区隧道比重、长度、埋深的加大,岩溶隧道涌水突泥、大型溶洞失稳等岩溶地质问题愈加突出,危害性大,风险极高,给隧道建设和运营带来了诸多困难。文章从施工地质、合理确定岩溶隧道地质测绘范围、合理选择铁路岩溶隧道空间位置、铁路岩溶隧道风险评估几个方面阐述了岩溶隧道勘察的重点和难点,以期为相关工程提供借鉴。With the acceleration of railway construction in China,the proportion,length and buried depth of tunnels in karst areas are increasing and in result the karst geological problems,such as water gushing,mud bursting and instability of large-scale karst tunnels,are becoming more and more prominent.A lot of harm and high risks will cause many difficulties to the construction and operation of tunnels.This paper expounds the emphases and difficulties of karst tunnel survey from the aspects of construction geology,reasonable determination of geological mapping scope of karst tunnel,reasonable selection of space location of railway karst tunnel and risk assessment of railway karst tunnel,in order to provide reference for related projects.
