摘要
Abstract
The Luojiacun Tunnel in the expansion project of Chuxiong-Dali Expressway is a three-lane and large-span tunnel.To ensure the smooth opening of the tunnel,it is necessary to first determine the stability of the mountain and then study the treat-ment measures for landslides at deep-cut trenches.Based on the results of on-site exploration,analyze the mutual influence be-tween the left and right tunnels,overall geological conditions,geological characteristics and rock strata orientation,and study the relationship between cave collapse and surface cracks,and verify it through numerical simulation.The research results indi-cate that the overall stability of the mountain is affected by construction disturbances and continuous collapse,which cause funnel-shaped creep along the tunnel bedding direction and generate surface cracks.Based on the research,relevant preventive and control measures are proposed,and the research results can provide reference for similar projects.关键词
