TSP系统在隧道超前地质预报中的问题及其改善处理

Problems with and Improvements to the TSP System for Advance Geological Forecasting in Tunnels

TSP系统作为一项比较成熟的超前地质预报技术,已被广泛应用在隧道施工过程中。文章以地震波反射理论为基础,简要介绍了TSP超前地质预报系统的工作原理及相应工作流程,总结了影响TSP预报效果的各种因素;并通过分析大量的TSP实测数据和典型案例,对该方法在数据采集、资料处理和解释等方面容易出现的各种问题进行了综合研究,提出了改善TSP系统超前地质预报可靠性的相应对策和措施,可为隧道超前地质准确预报提供参考。

As a proven technology for advance geological forecasting, the TSP （Tunnel Seismic Prediction） system has been used extensively in tunnel construction. This paper briefly describes the working principles and procedures of the TSP system in adwmce geological forecasting and summarizes various factors that affect TSP forecasting. Fur- thermore, based on the analysis of numerous measured data and typical cases, a study was carried out regarding the problems relative to dala collection, processing, and interpretation. Corresponding countermeasures to improve the re- liability of advance geological forecasting are put forward, which may be used as a reference for accurate advance gco-logical forecasting in the future.
