基于地层结构法的石子崎隧道施工过程模拟分析

Simulation Analysis of Shiziqi Tunnel Construction Process Based on Stratigraphic Structure Method

文章基于地层结构法,利用Midas GTS NX有限元软件,模拟了仁新高速公路上覆废弃建筑物的石子崎隧道开挖过程,对比分析了有无上覆建筑物两种工况下,隧道开挖过程中的沉降及衬砌内力分布规律,提出了隧道衬砌的重点监测位置,对隧道的施工及监控量测具有一定的参考价值。

Based on the stratigraphic structure method,this paper uses Midas GTS NX finite element software to simulate the excavation process of Shiziqi Tunnel with abandoned buildings overlying Renhua-Xinfeng Expressway.The distribution laws of settlement and lining internal force in the process of tunnel excavation is compared and analyzed under two working conditions with or without overlying buildings.The key monitoring locations of tunnel lining are put forward,which has certain reference value for tunnel construction and monitoring measurement.
