TGP12在隧道超前预报中的应用
The Application of TGP12 to Tunnel Prediction
【摘要】 超前预报可探明隧道施工前方复杂地质情况,为开挖方案的确定提供准确的依据。TGP12是利用地震波反射回波的原理对隧道进行探测的仪器,主要介绍其探测系统的原理、现场采集、数据处理、解释准则,并使用此仪器对罗岩二号隧道掌子面K61+130—K61+243里程处进行预报,结合实际开挖,证实了预报的可行性和准确性。
【Abstract】 Tunnel geology prediction may verify the complicated geological situation of the tunnel construction front,for the determination of the plan to provide the accurate basis.TGP12 is a tunnel prediction equipment by reflection of seismic wave.This paper mainly introduces the principle,field sampling,data processing,explanation technique of TGP12.TGP12 is used in the prediction for No.2 Luoyan tunnel at K61+ 130—K61 +243.Combining with the tunnel excavating,the result proves that TGP12 is an effective prediction technique in tunnel engineering.
