超前地质预报在海底隧道中的应用

The Application of Geological Extra-forecast in Construction of Submarine Tunnel

安全顺利穿过风化槽,是厦门海底隧道工程施工的难点和关键。施工中,通过TSP203、地质雷达、超前探孔等手段,对开挖工作面前方地质情况进行超前预报,尤其是F1风化槽的详细地质情况,为制定通过风化槽施工方案提供可靠依据。

Passing safely and smoothly through the weathered trough is Xiamen Harbour Crossing project＇s the most difficult and crucial point for the construction of submarine tunnel. In the process of construction, through TSP203, ground penetrating radar, advanced exploration holes, and other means, made geological forecasts before the excavation work carry out, particularly the detailed geological conditions of trough F1 weathered, and provide a reliable basis for the construction programme.
