【设备简介】TSP(Tunnel Seismic Prediction)超前预报系统是利用地震波在不均匀地质体中产生的反射波特性来预报隧洞掌子面前方及周围临近区域的地质情况。该法属多波多分量探测技术,可以检测出掌子面前方岩性的变化,如不规则体、不连续面、断层和破碎带等。实践表明该法有效预报距离100~200m。TSP超前预报技术作为一种比较先进的探测手段已在我国水利、水电、铁路、公路、煤炭等系统的各类隧洞或地下洞室工程中得到应用。它具有预报距离相对较长、精度较高、提交资料及时、经济等优点,尤其与隧洞轴线或呈大角度相交的面状软弱带,如断层、破碎带、软弱夹层、地下洞穴(含溶洞)以及地层的分界面等效果较好。
