TSP203(Tunnel Seismic Prediction)系统是由瑞士Amberg测量技术公司专门为隧道施工阶段超前地质预报而研发的一套设备。通过笔者单位的TSP法隧道超前地质预报工作,发现对隧道施工掌子面前方断层破碎带及其影响带的宽度范围、节理裂隙密集带等不良地质体TSP法能较准确地预报,但是在灰岩地区针对岩溶的准确预报存在一定困难,隧道施工因为在可溶岩地区而引发的各种灾害地质情况也时有发生,对隧道内的施工作业人员及设备构成很大威胁,所以准确预报隧道内掌子面前方的岩溶发育区域迫在眉睫,通过大量的实践和总结,在针对岩溶的准确预报方面笔者积累了部分经验,本文通过TSP在灰岩地区几个不同地质模型上的成功预报案例来详细讲解灰岩地区隧道施工中对岩溶的预报情况及其在长距离预报中的指导意义。
The TSP203 (Tunnel Seismic Prediction) system was developed by Amberg Surveying Technology AG in Switzerland for the purpose of advanced geological prediction of the tunnel construction phase. Through TSP method of tunneling in advance, we found that the TSP method can accurately predict the fault zone in front of tunnel face, the width range of influence zone, the dense geosynthetics with joint fissures, etc. However, There are some difficulties in accurately predicting the karst in the rock area. The geological conditions of the tunnel caused by the disastrous rock often occur from time to time, posing a great threat to the construction workers and equipment in the tunnel. Therefore, The karst development area in front of the face of the palm is imminent. Through a great deal of practice and conclusion, the author has accumulated some experience in the accurate prediction of karst. This article explains in detail the successful prediction cases of TSP in several different geological models in the limestone area Karst Prediction in Tunnel Construction of Limestone Area and Its Guiding Significance in Long Distance Prediction.
