摘要
由于受各种条件限制,隧道在前期设计勘察的时候往往不能完全真实地反映出地质情况,为了加强施工期间的安全工作,隧道在施工前应做好地质超前预报。本文在阐述了TGP与地质雷达技术的工作原理的基础上,结合兰新铁路的工程实例利用各自成像波形图和成果图分别进行地质超前预报,进而对两种预报方法作出对比分析。
Due to various constraints, the tunnel in the early design of the survey was not fully reflect the geological conditions, in order to strengthen the construction of geological work in the construction, Tunnel geological advanced forecast should be done before construction, This paper elaborate the TGP and gedogical, and works with engineering examples of Lan-Xin railway, make a geological advanced prediction respectively based on the respective imaging waveform diagram and achievement chart, then make a comparative a- nalysis between the two methods.
