| 摘 要： | 文章基于结构-荷载理论对城市下穿式矩形框架隧道进行结构模型简化,同时利用有限元软件ANSYS对隧道进行了结构力学分析。分析结果表明矩形框架隧道在拐角处受力最不利,需在结构的设计及施工中根据结构截面强度验算进行配筋加厚处理,以保证隧道结构的安全。

| Abstract: | The article simplify the city rectangular framework tunnel model based on structure-loading theory.It also uses finite element software ANSYS to perform structure mechanical analysis on tunnels.The analysis result shows that the rectangular framework is in most dis-advantageous situation at the corner.The reinforcement thickening treatment needs to be done after calculating the section strength calculation during structure design and construction,to make sure the safety of tunnel structure. |
