新建建筑对既有轨道交通隧道影响安全评估分析

Safety Assessment on the impact of building a new construction on the exsiting rail transit tunnel

以实际工程为例,运用有限元软件ANSYS,建立三维与二维地层结构法模型,计算分析既有轨道交通结构保护区内新建建筑结构对轨道隧道结构变形与内力影响,从而评估新建建筑实施对轨道结构的正常运营与安全性。

Based on the actural engineering,models of stratigraphic texture of 2- D and 3- D are built with the ANSYS finite element software,then the impact of building a new construction structures in the rail transit tunnel protected area on deformation and internal force of tunnel is analyzed. Therefore the impact of building a new construction on normal operation and safety of rail structure is evaluated.
