摘要： 结合大丘林2号隧道施工过程，通过长距离的TSP探测和短距离的地质雷达探测，预报前方围岩的地质条件和失稳的可能性，通过对拱顶沉降、围岩收敛、钢拱架内力和围岩压力的监测，有效的预报围岩失稳灾害的发生，其成功的经验可为类似工程提供参考。

Abstract: The Daqiulin 2nd Tunnel is a separated bidirectional fourlane highway tunnel. Due to the unfavorable geological as well as topographical conditions, the potential construction interruptions resulted from the instabilities of the rock mass, could have lengthened the construction schedule and increased the investment. During the construction of this tunnel, the instability of the rock mass was forecasted with the both the Tunnel Seismic Prediction (TSP) form the long distance and the Ground Penetrating Radar (GPR) in the short distance. The deformation of the tunnel roof and the surrounding rock mass; the stresses in the supporting system and in the rock mass were also monitored. The construction safety is able to be warranted.
