摘要
以山西平阳高速公路阳曲1号隧道为工程背景,对黄土隧道进行了研究。利用Midas/GTS有限元分析软件,建立三维有限元模型,分析了阳曲1号黄土隧道开挖支护后的位移场,并与现场监测数据进行了分析对比,隧道开挖数值模拟与围岩监测结果基本一致,说明支护参数合理,为黄土隧道的建设积累了经验。
This paper,taking No.1 loess tunnel at Yangqu in Pingyang Expressway as an example,studied the loess tunnel.By using the finite element software MIDAS/GTS and by setting up three-dimensional finite element model,this paper analyzed the displacement field of the loess tunnel after being excavated and supported.Then in comparison with site monitoring,it is concluded that the numerical simulation data is generally in accordance with the data of site monitoring of the surrounding rock,and the support parameters is reasonable.This study can also serve as an example to gather experience for loess tunnel construction.
