在岩溶隧道施工中对掌子面前方一定范围内的地质情况进行超前探测和预报是保证隧道施工安全的有效措施,本文采用地质雷达法结合地质素描对岩溶隧道超前地质预报进行了全面的总结。采用该技术,成功预报并穿越了某隧道岩溶突泥处,并给出了各种典型岩溶空腔的雷达典型曲线。关系隧道安全、顺利贯通,证明了该技术的实用性和有效性。
In the karst tunnel construction, the advanced detection and forecasting of the geological conditions in front of the face of the face is an effective measure to ensure the construction safety of the tunnel. This paper summarizes the advanced geological prediction of the karst tunnel by the method of geological radar and the geological sketch. Using this technique, the prediction and traversal of a tunnel karst mudstone were successfully predicted, and the typical radar radars of typical karst cavities were given. The safety of the tunnel is well connected and it proves the practicability and effectiveness of the technology.
