TSP203在灰岩地区隧道施工过程中的应用与探索

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。

Application of TSP203 to Limestone Areas of Tunnel Construction

TSP203（Tunnel Seismic Prediction）system is carried out by Amberg Measuring Technologies Corporation, which is used for the advanced geological predication in the tunnel construction. After using this system, we find it is good at inspecting fault zone, but difficult for Karst problems in tunneling. For the tunnel is built in limestone areas, the geologic hazard can not be avoided because of Karst problems,which will threatened the safety of people and equipment. Therefore, it is very important to predict the karst development areas of the tunnel face correctly. This paper will introduce some successful predicted cases of different geological models to illustrate the predicated condition of karst and the significance of long-distance predication.
