摘要
广州国际金融城起步区区内地下环路具有体量大、跨度大、结构受力大、空间关系复杂等特点。文中介绍了深覆土区段的结构选型、风道结构形式的选择、毗邻综合管廊的结构方案这三个难点,并通过Robot软件进行了建模分析,结果表明不同的结构选型对受力合理性和工程经济性影响较大。最后结合工程设计经验给出设计建议,可为相似工程设计提供参考依据。
The underground ring road in Guangzhou International Financial City Starting Area has the characteristics of large volume, large span, heavy loads on structure and complex spatial relationship. In this paper, the three difficulties of structural form selection of thick overburden soil segment, structural form selection of air duct, and structural scheme of Underground Ring Road which is adjacent to urban utility tunnel were expounded. The modeling analysis was carried out by Robot software. The results show that different structural types have great influence on the rationality of force and engineering economy. Finally, some suggestions were given based on engineering design experience, which could provide reference for similar engineering design.
