偏压及沟谷地形条件下黄土隧道力学特性分析

The Analysis of Loess Tunnel Mechanical Properties under the Conditions of Bias and Valley Terrain

为深入分析偏压及沟谷地形条件下黄土隧道力学特性,选取典型偏压及沟谷地形条件下的隧道段,结合现场搜集的地形资料,利用有限元数值模拟软件,模拟隧道在该地形条件下的初期支护应力应变的规律。

For further analyzing loess tunnel mechanical properties under the conditions of bias and valley terrain,this paper chose the typical tunnel sections,combined with field collection of terrain data,simulated the tunnel initial support stress-strain rule by the finite element numerical simulation software.
