摘要
隧道工程地质条件具有复杂性和不可见性,隧道施工安全问题愈加引发关注。超前地质预报是保证隧道施工安全的重要环节和技术保障,可准确掌握隧道开挖前方地质状况,最大限度避免隧道地质灾害发生。文章以东沟隧道为研究案例,采用地质调查法、TSP法和地质雷达法,综合分析物探成果,预报隧道施工前方地质情况及围岩级别,为后期施工安全、设计变更提供物探依据,指导施工设计,保障施工安全。
The geological conditions of tunnel engineering are complex and invisible,and the safety issues of tunnel construction are increasingly concerned.The advanced geological forecast is an important link and technical guarantee to ensure the safety of tunnel construction,which can accurately grasp the geological conditions ahead of tunnel excavation and minimize the occurrence of geological disasters in the tunnel.Taking Donggou tunnel as the research case,the geophysical prospecting results are comprehensively analyzed by using the geological survey method,TSP method,and geological radar method,and the geological conditions and surrounding rock level before tunnel construction are forecasted,so as to provide the geophysical prospecting basis for later construction safety and design changes,guide the construction design and ensure construction safety.
