摘要
针对大断面高速铁路隧道施工过程中出现的复杂施工力学问题,以花甲山高速铁路隧道为依托工程,采用三维数值软件对花甲山隧道的施工动态过程进行数值模拟,得到了隧道围岩的应力、位移分布特征和地表变形规律,通过与现场实测数据进行对比,总结出大断面高速铁路隧道的动态施工力学特征,为大断面高速铁路隧道施工方案优化提供依据.
As the construction mechanics characteristics of large cross section high speed railway tunnel is complex, the dynamic construction process of Hua jia shan tunnel is simulated by using three-dimensional numerical software. The stress and displacement characteristics of rock mass and surface deformation law are obtained. By comparing with field measured data, the dynamic construction mechanical characteristics of large cross section high speed railway tunnel are concluded which provides support for construction scheme optimization of this project.
