地铁风亭围护结构优化设计

Optimized Design of the Enclosure Structure of Metro Wind Pavilion

基于广州某地铁车站狭长型风亭围护结构设计,通过调整风亭支撑布置及地连墙分幅宽度,对风亭施工步序进行优化。经计算,优化后的方案围护结构受力满足要求。该优化措施造价减少,工期缩短,且提出了狭长型风亭围护结构设计的原则和新思路,可为地铁结构设计提供一定的经验和借鉴。

Based on the design of the narrow and long wind pavilion enclosure structure of a subway station in Guangzhou,this paper optimizes the construction steps of the wind pavilion by adjusting the support layout of the wind pavilion and the width of the underground diaphragm.After calculation,the envelope structure of optimized scheme fulfills the requirments for force bearing,the cost is reduced,and the construction period is shortened with this optimization measure,and the principles and new ideas of the design of the long and narrow wind pavilion envelope structure are put forward.
