摘要
我国是一个多山的国家,山区的铁路建设需要修建大量隧道,并向深埋、长大方向发展。随之而来的地质问题也会更为复杂化,超前地质预报在隧道施工中变得尤为重要。本文则提出以地质调查法为基础,以地震波法做长距离预报,局部异常段采用水平声波反射法(HSP)进行中长距离复核探测,以地质雷达法和红外探水法进行短距离精确预报的综合预报方法。通过对贵州—广州高速铁路三都隧道的应用研究,本方案取得了很好的预报效果,给施工单位提供了有效科学的指导。
China is a mountainous country.So for railway construction in mountain areas,lots of tunnels are needed to be built.As the geological conditions become more and more complicated,it is very important to apply the advanced geological forecast technique to constructing tunnels.In this paper,it proposes an integrated forecasting method,which is based on geological survey method,and uses TSP for the long distance forecast,HSP for the mid-long distance forecast in local anomalies section,GPR and infrared detector for accurate forecast of the short distance.This integrated method has obtained a good result when it is applied to the construction of Sandu tunnel on GGTJ-2 for research,and has provided an effective and scientific guidance for the construction.
