摘要
隧道施工过程的应力和位移的变化是施工中十分关注的问题,目前对于这一问题数值模拟分析多基于简化的平面应变问题进行模拟,由于平面应变问题的特点决定了,采用此种方法无法反映隧道施工过程中的空间力学效应。该文结合上坡双连拱隧道,对隧道的施工过程进行了三维数值模拟,得出一些有益的结论,这些结论可以作为理论研究和施工实践的参考。
The stress and displacement change are concerned during the tunnel construction process.At present,Numerical simulation used to solve this kind of delimma is based on the plane strain problem.Because of the plane strain characteristics,This method can not reflect the spatial mechanics effect in the tunnel construction process.Based on Shangpo double arched tunnel,the paper carries 3D numerical simulation of construction of this double Arched Tunnel and draws some beneficial conclusions.These conclusions can be used as reference on theoretical research and construction practice.
