TGP206地质超前预报系统在隧道施工中的应用
|
摘要
复杂地质条件下的隧道施工中,如何探明地质情况,选择合理开挖方案,关系到隧道施工的顺利进行,超前地质预报的作用显得尤为重要。本文结合隧道工程实例,介绍TGP206型地质超前预报系统的原理、数据采集、数据处理、成果解释技术;通过与开挖后地质情况对比,检验预报结果的可信度;并提出实践中遇到的一些问题,以供讨论,为以后类似工程的开展提供经验。
Under complicated geological conditions in the tunnel construction,How to prove geological conditions,choice a reasonable excavation programme,relating to the smooth progress of construction of the tunnel,advanced geological forecast is becoming more and more important.In this paper,with examples of a tunnel project,Focusing on TGP206 geological forecast system theory,data processing,interpretation of test results,contrasting with the geological conditions after digging,testing the credibility of forecasting results;And show some problems encountered in practice,for discussion,In order to provide experience for the similar projects in the future.
