TSP-203超前地质预报在隧道斜井涌水探测中的应用

On the Application of the TSP-203 Advanced Geological Forecasting to the Detection of Water Inflow in Inclined Shafts for a Tunnel

介绍了TSP-203超前地质预报探测技术的工作原理、系统组成,现场数据采集的程序及在此过程中应注意的问题等;结合在斜井涌水探测中的应用实例,进行了具体的数据解译,并据此预测了可能发生涌水的位置,并及时启动了应急预案,成功的完成了斜井的开挖施工。可为隧道施工超前地质预报工作提供参考。

The working principle,the systematic composition and the site data-collecting processes of the TSP-203 Advanced Geological Detecting and Forecasting,and points for attention in the course of the site data-collecting are introduced in detail in the paper.With practical problems in the application of the detecting technique to detect water inflow in the inclined shafts as examples,the data collected are numerically interpreted,upon the basis of which the possible spots of water inflow are forecasted,with the preparatory emergency schemes timely carried out and the excavation of the inclined shafts successfully performed.The paper may serve as a useful reference for the advanced geological forecasting for tunnel construction.
