单排树形大悬臂墩柱高架轻轨车站结构设计

Structural design of light railway station supported by tree-shaped colonnade with long cantilever

介绍一种新的由单排树形大悬臂墩柱支承的桥建合建结构体系,该体系是将桥梁设计中温度应力的处理方法与独特的墩柱造型相结合,实现了城市主干道上高架轻轨车站设计三要素即城市景观设计、建筑功能和结构力学的完美统一,已成功应用于广州地铁四号线黄阁汽车城站的结构设计,创造了较好的经济效益和社会效应。

A new structural system named ＂hybrid structure of bridge and building＂ supported by tree-shaped colonnade with long cantilever is introduced. It is incorporated by the technical measures to reduce temperature stress in bridge design and the unique colonnade style to realize the integration of landscape design, architectural design and structural mechanics in the construction of elevated light railway station on primary highway in city. It has been successfully applied in the the structural design of Huangge automobile city light railway station in Guangzhou metro No. 4 and produced economic efficiency and social effect.
