某隧道地质灾害分析及应对措施

Analysis of a tunnel's geological disasters and countermeasures

针对隧道地质情况和涌水灾害情况,采取了地质雷达,TSP203超前探测等综合技术确定了涌水段的地质状况和涌水原因,根据探测结果和实际条件,采取了先处理坍腔,并开挖通过涌水段,然后再对突涌水处进行注浆堵水的技术措施,安全通过了此段,保证了工期。

Acoording to the conditions of a tunnel＇s geological disasters and water-pouring, it adopts geological radar and TSP203 superior exploiting skill to fix the geological condition and water-pouring reasons. According to the expoiting results and actual conditions, it adopts firstly＇ collapse-processing, and digs the water-pouring section, then makes water pouring skill measures and passes this section safely, so as to ensure the working period.
