Tunnel Seismic Prediction (TSP) and its Application in Tunnel Engineering

Abstract:

In order to avoid heavy casualties and economic losses, and to get an insight into engineering and hydrogeological conditions, Tunnel Seismic Prediction (TSP) method is applied for advanced geological prediction in tunnel engineering. Basic principle, data analysis method, prediction criterion of TSP are studied. Seismic reflection characteristics of karst caves and fractured zones are analyzed and demonstrated in Qiyueshan Tunnel. Results indicate that TSP is sensitive to karst caves and fractured zones, but may have errors in location. The location of the prediction results should be checked with comprehensive geological prediction methods. In some extent, research of the prediction principles and engineering application in the present study is instructive for further applications.
