摘　　要：利用隧道地质超前预报系统(TSP)203设备对太锡铁路太崇段和平隧道及崇礼隧道进行了超前地质预报工作。分析既有地质资料,利用物探手段,在隧道开挖前,对工作面进行提前探测、预报及分析并提出措施建议,帮助项目选择正确的开挖技法,调整合理支护参数和优化施工方案等提供数据依据。为了预防隧道涌水、泥突、围岩突变等可能形成的灾害事故提前进行预报,以便于项目做好预案,让施工安全得到保障。研究TSP203设备的便捷性、稳定性、高效性。Tunnel seismic prediction(TSP)203 equipment was used to carry out advance geological forecast for the heping tunnel and Chongli Tunnel of taichong section of Taixi Railway.By analyzing the existing geological data and using geophysical prospecting methods,the working face was detected,forecasted and analyzed in advance before the tunnel excavated,and the measures and suggestions were put forward to help the project select the correct excavation techniques.The data could be provided by adjusting reasonable support parameters and optimizing construction scheme,inorder to prevent water gushing,mud outburst,sudden change of surrounding rock and other disasters in advance,so as to make a good project planning,so as to ensure the safety of construction.The convenience,stability and efficiency of TSP203 equipment were also studied.

关 键 词：隧道地质超前预报系统 超前地质预报 安全高效
