| 摘 要： | 为分析地下商场对其正下方大跨轻轨隧洞的安全影响,用有限元程序模拟在地下商场的施工开挖和建成受荷过程中隧洞衬砌的应力和位移变化情况,计算结果表明,地下商场的修建对隧洞的稳定性没有影响,水平方向的位移较小,而较大的竖向位移也对隧洞的正常营运影响不大。

| Abstract: | To analyze the underground marketplace's effect on the undelying large-span tunnel's safety,FEM is used to simulate the changes of stress and strain in the liner throughout the underground marketplace's construction,the results show that the marketplace's construction wouldn't affect the liner's reliability and the bigger displacement in vertical direction than in horizontal wouldn't affect the tunnel's function. |
