摘要
近年来,随着我国山岭地区基础建设不断拓展,铁路隧道衬砌的破坏变形成为隧道施工中最具有危害的问题之一,关乎隧道施工的结构安全性,而国内这方面相关的研究成果较少,因此,亟需展开铁路隧道结构衬砌受力特性的研究。本文以某铁路隧道为例,运用数值模拟分析,探究铁路隧道衬砌的结构受力特性,取得了一些重要研究成果。
In recent years,with the continuous expansion of infrastructure construction in mountainous areas of China,the destruction and deformation of railway tunnel lining has become one of the most dangerous problems in tunnel construction and it is related to the structural safety of tunnel construction,and the relevant research results in this aspect in China are more less,therefore,it is urgent to carry out research on the mechanical characteristics of railway tunnel lining structure.Taking a railway tunnel as an example,this paper uses numerical simulation analysis to explore the structural stress characteristics of railway tunnel lining,and has achieved some important research results.
