摘　　要：地下综合管廊是城市重要的基础设施,保障着城市的正常运行。近些年自然灾害时有发生,地震对地下结构的破坏最为严重。所以对于重要的地下基础设施,应进行抗震设计。本文采用Midas-gen软件,根据反应位移法计算标准断面横向水平地震作用。利用理正结构设计工具箱软件,采用平面刚桁架模型计算标准断面的承载能力极限状态及正常使用极限状态。对比非地震工况内力与地震工况内力可知:本工程地震工况不起控制作用,应以承载能力极限状态计算的内力进行截面设计,并对正常使用极限状态进行校核验算,同时采取抗震构造。Underground comprehensive corridor is an important infrastructure to ensure the normal operation of the city.Natural disasters have occurred frequently in recent years,and earthquake damage to underground structures is the most serious.Therefore,seismic design should be carried out for important underground infrastructure.In this paper,Midas-gen software is used to calculate the transverse horizontal seismic action of standard section according to the response displacement method.The limit state of bearing capacity and normal service limit state of standard section are calculated by using Lizheng Software structural design toolbox software and plane rigid truss model.By comparing the internal force under non-seismic condition with that under seismic condition,it can be seen that the seismic condition of the project has no control function,so the section design should be carried out based on the internal force calculated under the ultimate state of bearing capacity,checking and calculating the normal service limit state,and adopting the seismic structure at the same time.
