［摘要］文昌鲁能淇水湾度假综合体为二层钢框架结构，由于使用原因需进行移位。项目场地地质情况和自然条件多变，建筑物体型复杂，移位方式多样，包含平移、转向和顶升，为提高其抗震性能就位后需隔震连接，设计难度加大。托换采用了带有转换梁的托换方式，减少了轨道数量，降低了工程造价； 以短期沉降控制为目的，基础采用了多种桩基与天然地基的组合； 移位时利用可重复使用的钢构件体系作为工具，结合场地标高进行了分次顶升； 设计了移位施工过程中的抗风措施； 提出了一种既有钢柱增加隔震支座的连接方式。

Abstract:Wenchang Luneng Qishuiwan Resort complex was a two-story steel frame structure, and had to be integrally displaced due to use reasons. The geological and nature condition of the project site was changeable, building shape was complex, and displacement methods were varied including translation, rotation and jacking. In order to improve seismic performance, seismically isolation connection was needed after building displacement, which increased design difficulties. Underpinning structure with transfer beam was adopted to reduce the number of tracks and the cost of the project. For the purpose of short-term settlement control, the foundation was composed of several pile foundations and natural foundation. In the process of displacement, the reusable steel member system was used as a tool, and the elevation of the site was lifted in several times. The wind resistance measures in the process of displacement construction were designed. A connection method of the existing steel column isolation bearing was proposed.
