TSP超前地质预报在城市轨道交通暗挖隧道中的研究与应用

The Research and Application of TSP Geological Advance Prediction in Subsurface-excavated Tunnels of Urban

城市轨道交通隧道施工期间,TSP超前地质预报可作为地勘资料的补充指导施工。通过分析大量TSP实测数据,对各种可能产生异常信号的原因以及避免产生和接收到异常信号的措施进行了研究。并且论述了一个TSP技术在城市轨道交通暗挖隧道中的应用实例,经后期开挖验证,TSP技术在城市轨道交通中取得了较好的效果,对施工过程中即将出现的地质危害起到了提前预警的作用,值得进一步推广。

During the tunnel construction in urban rail transit,TSP geological advance prediction can be taken as supplement of geological exploration data to guide the construction. By analyzing a lot of TSP measurement data,this paper studies the reasons for the abnormal signals generated and the measures to avoid generating and receiving abnormal signals. The paper also discusses an application example of TSP technology in subsurface-excavated tunnels of urban railway system. Verified by later stage of excavation,TSP technology has achieved good results in urban rail transit. , and played the role of early warning of impending geological hazards in construction. So it is worthy of further promotion.
