摘要
隧道突水是岩溶地区隧道信息化施工过程中经常遇到的一类地质灾害,给施工安全带来了重大危害和经济损失,因此,对隧道掌子面前方的岩溶裂隙水进行准确及时的超前预报,是岩溶地区隧道动态设计与信息化施工中亟待解决的重要问题,具有重要的理论意义和重大的工程实用价值。总结了隧道信息化施工中岩溶裂隙水超前预报方法,重点介绍了在水文地质分析的基础上,综合运用TSP预报系统和红外探水法两种方法对某特长公路隧道岩溶裂隙水进行了工程实例探测,收到了良好的预报效果,对类似工程具有一定的指导意义。
A kind of geological disasters such as water bursting often occurs in karst area in the process of informational construction of tunnel, which bring momentous disaster and economic loss to construction safety, so the precise and immediate advance forecast to the development of karst is the key problem to be researched and resolved currently in tunnel dynamic design and informational construction in karst areas, which brings important theoretical significance and practical value. The method of forecasing karst-fractured groundwater in tunnel informational construction is firstly summed up, then TSP and infrared water detecting method are used synthetically to detect a special long road tunnel based on hydrogeological analysis, which gains good prediction results. It has guiding significance to similar projects.
