| 摘 要： | 以浙江上三线高速公路隧道为工程背景，应用大型有限元软件MARC对洞口段隧道进行动态施工全过程三维有限元模拟。分析了施工工序，工艺对隧道拱顶沉降，侧壁收敛变形的影响，全面追踪了动态施工中隧道关键部位的变形过程，并基于弹性－粘弹性对应性原理，由各向同性及横观各向同性弹性计算的变形结果预测隧道的粘性变形。

| Abstract: | Based on the project of expressway tunnel in Zhejiang Province,the entire dynamic construction process of the tunnel is simulated by 3-dimention finite element method with MARC software.The influence of construction procedures and construction techniques on settlement of arch crown and contracted displacement of side-wall are studied,which traces the procedure of the displacement of the important area under the entire dynamic construction.In terms of the principle of correspondence of elasticity to viscoelasticity,the creep displacement of tunnel is predicted on the basis of the results of elastic analysis which are done with isotropic and transversely isotropic stress-strain model. |
