摘要
我国中西部及两广地区广泛分布岩溶地貌,对其中隧道施工影响显著。全面深刻认识溶洞对隧道施工变形规律的影响,有利于控制隧道稳定、确保施工安全。文章基于实际工程,采用数值模拟手段,探讨了溶洞在隧道不同位置、不同距离下隧道及围岩变形特征。
Karst landform is widely distributed in central and western China and Guangdong,which has a significant impact on tunnel construction.It is beneficial to control the stability of the tunnel and ensure the safety of the tunnel to ensure the safety of the construction.Based on the actual project,this paper discusses the deformation characteristics of the tunnel and surrounding rock of the karst cave at different locations and different distances of the tunnel by means of numerical simulation.
