隧道浅埋段地表沉降监测评价研究

Evaluation of Surface Subsidence Monitoring in Shallow Sections of Tunnel

依托草坪子隧道浅埋暗挖段地表沉降监测项目,对隧道浅埋暗挖施工过程中引起的地表沉降进行了监测,探讨了隧道开挖引起的地表沉降机理,分析了隧道开挖作用下常见的地表损害形式,最后模拟分析监测结果对此次监测方案进行评价得到此浅埋段隧道的地表沉降随隧道开挖的规律以及本身的累计沉降规律。

Based on the lawn the tunnel shallow tunnel section surface subsidence monitoring project, the shallow tunnel construction of the tunnel in the process of surface subsidence caused by monitoring, this paper discusses the mechanism of ground subsidence caused by tunnel excavation, the tunnel excavation is analyzed under the action of common form of surface damage, the simulation analysis of monitoring results to evaluate the monitoring scheme to get the stu-face settlement over the period of shallow buried tunnels are the rule of tunnel excavation and the cumulative settlement law of itself.
