摘要
结合工程实践利用有限元原理,应用大型有限元软件计算了平顶隧道覆土层内管线的受力状态,并根据管线的实际情况进行了安全判别,结果正确、数据可靠,指出利用有限元计算对施工有着很重要的指导意义。
According to nonlinear FEM principle and using large-scale FEM software in this article, The stress of pipe are obtained in fiat-top tunnel earth coveting. At the same time, we define pipe safety or danger through practical situation, this study is very important for constmction.
