地铁半幅铺盖体系设计与分析

Design and Analysis of Cover System with Half-width in Subway Station

以实际工程为例,通过介绍临时路面铺盖系统的类型、铺盖系统的设计过程、计算结果、工程造价、优缺点、施工便捷性,较为全面地对各个铺盖系统的特点、尺寸要求、相关规范规程、相应的应用手册等对其进行分析和阐述.综合考虑实际工程中边界条件,自然因素等对初步设计阶段、施工图设计阶段的过程进行描述,总结出工程设计过程中铺盖的选型、计算、应用范围等,为类似的(以较小跨度铺盖为主)地铁铺盖设计选型提供借鉴,并提出相对合理的建议.

Taking the actual project as an example.,the author introduced the type of temporary pavement cover system,the design process of the cover system,the calculation result,the project cost,the advantages and disadvantages,the construction convenience as well as more comprehensive description of the characteristics,size requirements,relevant specifications,procedures,and corresponding application manuals of each cover system.In views of the boundary conditions and natural hctom in the actual project,the process of the preliminary design stage and the construction drawing design stage were described,the selection of cover system type,calculation and application range of the project design process were summarized,which would provide reference for similar(small span spanning)metro covering system design and selection,and some relatively reasonable suggestions were put forward.
