[摘要]  对于住宅开发项目，一般要求主楼形象进度达到总高度的三分之一以上才符合预售条件，为了尽早达到上述条件，工程施工顺序经常是先主楼后地库。在建筑专业满足配建停车位指标及人防建设面积等要求的前提下，结构如何处理主楼与地库的衔接对于工程工期、施工难度及成本控制等都有着重大影响。本文以徐州新城区A3-2地块项目为例，浅析高层住宅主楼与地库分离布置方式的选定与结构处理。

Abstract：Generally speaking, for residential projects, when the description of construction progress meets more than 1/3 of the total height, the project can be pre-sale. In order to meet the above conditions as soon as possible, the construction sequence is usually from main building to underground garage. When the limited number of parking space and the area of civil air-defense construction meeting the requirements, how to deal with the sequencing of main building and underground garage has great influence on construction period, construction difficulty, cost control and so on. This paper takes block A3-2 in New District of Xuzhou for example, analyzing the mode selection and the structure processing, under the condition of main building and underground garage be separated as a typical representative of high-rise building.

Keywords：underground garage, construction sequence, separated
