| 摘 要： | 以拟建的哈尔滨松花江隧道为例,直接针对隧道安全运营,采用因子对目标函数影响的优化思想,在假定不同工况的若干种设计模型下,考虑土体-衬砌相互作用及材料变形的非线性特性,建立尽可能逼近实际问题的有限元计算模型.基于 ANSYS 软件反复进行数值模拟实验,研究隧道周围土体及衬砌变形的力学性状,并据此预估隧道最危险破坏点,为合理确定隧道覆土层安全厚度提供理论依据.

| Abstract: | For Songhua River tunnel to be buih in Harbin optimization of factors influencing the target function is adopted to ensure normal and safe work of the tunnel,and the finite element analysis is employed to simu- late the actual problem using the software of ANSYS,with nonlinearity of material and soil-liner interaction taken into consideration.The mechanic behavior of wall soil and liner of underwater tunnel are studied by a great lots of numerical simulation experiments and the location of the most dangerous failure is assessed before- hand,which provides some theoretical basis for determining the safety layer thickness of tunnel properly. |
