摘要
结合张家口至石家庄高速公路北口隧道进口段工程,运用MIDAS/GTS软件建立了原始边坡-隧道-路堤边坡三者耦合的仿真三维分析模型,对北口隧道进口工程不同工况下坡体的稳定性进行了分析,并得出隧道开挖和路堤修筑过程中原始坡体位移和应力的变化规律,对于工程实践有一定的意义。
Combined with the project about the entrance to north tunnel of expressway from Zhangjiakou to Shijiazhuang, this paper uses the MIDAS / GTS software to build a three dimensional analysis simula- tion model of the original slope, tunnel and embankment slope. It analyzes the stability of the slope body at entrance to north tunnel under different conditions. At last, the paper gets the variation regular about the original slope displacement and stress in the process of the tunnel and embankment construction, which has some reference to the project in practice.
