摘要
随着双碳目标上升为国家战略,建设绿色低碳隧道已成为目前我国隧道重点发展方向。传统隧道超前地质预报技术,采用乳化炸药爆破作为地震波震源,不符合双碳理念,且存在安全隐患。HSP隧道超前地质预报技术采用非爆破震源,低碳环保,不仅能在钻爆法隧道施工中应用,而且在TBM及盾构隧道中也可使用。通过有限元法对隧道中地震波的传播进行正演模拟,并运用HSP隧道超前地质预报系统分别在钻爆法及盾构隧道中进行现场试验,验证非爆破震源方法进行隧道地质超前预报的可行性及有效性。最后将非爆破震源HSP法地质预报技术应用于在建钻爆法和盾构法施工隧道,有效预报了掌子面前方不良地质体,应用效果良好,对绿色低碳隧道施工地质预报具有借鉴意义。
With the dual carbon goal becoming a national strategy,the construction of green and low-carbon tunnels has become the key development direction of tunnels in China.The traditional tunnel advance geological prediction technology,which uses emulsion explosive blasting as the seismic source,does not conform to the concept of double carbon,and there are potential safety hazards.HSP tunnel advanced geological prediction technology adopts non blasting source,low-carbon and environmental protection,which can be used not only in drilling and blasting tunnel construction,but also in TBM and shield tunnels.In this paper,the propagation of seismic waves in the tunnel is simulated by the finite element method,and the field tests are carried out in the drilling and blasting method and the shield tunnel by using the HSP tunnel advance geological prediction system,which verifies the feasibility and effectiveness of the non blasting source method for tunnel geological advance prediction.Finally,the geological prediction technology of non blasting source HSP method is applied tunnel construction by drilling and blasting method and shield method,which effectively predicts the adverse geological body in front of the tunnel,and the application effect is good,which has reference significance for the geological prediction of green low-carbon tunnel construction.
