摘要
在隧道开挖过程中 ,对掌子面前方岩性进行比较准确的预报 ,可有效地防止工程事故、加快施工进度以及保证工程质量。目前常用的地质超前预报方法可归为破坏法和非破坏法两类 ,各有其优缺点 ,其中非破坏法中的TSP(TunnelSeismicPrediction)隧道地震波预报技术具有预报距离长、预报费用低和探测时间短等独特优越性。据此 ,本文对TSP技术原理和数据采集、处理系统作了介绍 。
During tunneling, the precise prediction of rock properties ahead the tunnel face can effectively prevent the engineering accidents, improve construction progress and assure the project quality. The applied methods of geological prediction for tunnels are summarized into crack methods and non crack methods with their advantages and disadvantages. Among non crack methods, the Tunnel Seismic Prediction (TSP) has specific advantages such as long prediction distance, low prediction fee and short operation time etc. In this paper, the TSP principle along with the system of data acquisition and analysis is introduced. Some successful applications of TSP in tunnel construction are listed in the end.
