某工程综合管廊吊装口应力分析方法对比研究

An analysis of the stress of the urban utility tunnel lifting port

城市综合管廊作为一种可同时容纳多种管线于一体的市政基础设施,在城市化进程中扮演着越来越重要的角色。吊装口是管道及附属设备、管廊运行维护设备、管廊二次浇注材料等进入管廊内部的通道,是综合管廊工程中必须设置的重要节点。以某双舱断面综合管廊工程为例,对吊装口分别采用平面框架法、简化平板法及三维有限元法进行内力分析,并给出了3种计算方法下的内力差别,可为类似综合管廊吊装口设计分析提供一定的参考。

As a municipal infrastructure,urban utility tunnel plays an important role in the process of urbanization.The lifting port is the channel for pipes and auxiliary equipment,pipe corridor operation and maintenance equipment,etc.to enter into,which is an important node in urban utility tunnel.The paper gives the differences of three different analytic methods of the plane frame method,simplified flat plate method and 3-D finite element numerical analysis method,which can provide a reference for the related design.
