高速公路隧道施工动态监测与有限元数值模拟分析

Dynamic Monitoring and FEM Simulation Analysis in Highway Tunnel Construction

以广贺高速公路某隧道工程为背景,在现有隧道动态监测与数值模拟的基本理论方法的基础上,建立有限元模型,研究了隧道施工过程中围岩的位移变化规律。通过数值成果与隧道围岩位移实测值的比较,认为数值模拟分析中得到的施工过程中隧道围岩位移场变化规律基本与实际相符合,从而便于更好地开展施工监控和施工指导工作。

Taking Guang-He highway tunnel as background, this article established the FEM example and study of the displacement of adjacent rock in tunnel construction based on the dynamic monitoring and simulation analysis theory. Through the comparing between practical survey and FEM, we can get the displacement of adjacent rock in simulation analysis. It is agreed with practical situation.
