［摘要］簡述了車輛段上蓋開發(fā)項目的工程概況，指出目前對于抗震8度區(qū)車輛段上蓋小高層住宅開發(fā)項目較多采用層間隔震結(jié)構(gòu)的現(xiàn)狀。通過北京地鐵16號線榆樹莊停車場項目的結(jié)構(gòu)對比計算，以及已建北安河車輛段的經(jīng)濟(jì)對比分析，結(jié)果表明此類項目采用層間隔震結(jié)構(gòu)與采用框架+支撐結(jié)構(gòu)是各有利弊的。通過6度區(qū)杭州仁河車輛段項目簡述了框架+支撐結(jié)構(gòu)相對層間隔震結(jié)構(gòu)具有更廣的應(yīng)用范圍。最后，總結(jié)了框架+支撐結(jié)構(gòu)車輛段上蓋住宅開發(fā)項目的結(jié)構(gòu)選型，并針對小高層住宅開發(fā)項目總結(jié)了主要設(shè)計要點及優(yōu)化思路，給予類似工程設(shè)計一定的啟迪與借鑒。

Abstract:The project overview of the metro depot upper-cover development project was briefly described, and the current situation that the interlayer seismic isolation structure was mostly used in the metro depot upper-cover development of small high-rise residential buildings in the area with 8 degree of seismic fortification intensity was introduced.Through the structural calculation of Yushuzhuang parking lot project of Beijing Metro Line 16 and the economic comparison with already-built Bei′anhe Metro Depot, the results showed that there are both advantages and disadvantages between the use of interlayer isolation structure and the use of frame+support structure in such projects. Through the analysis of Hangzhou Renhe Metro Depot project in the 6 degree of seismic fortification intensity, the wide application range of the frame+support structure compared to the interlayer isolation structure was briefly described. Finally, the structural type selection of the residential development project above the metro depot of the frame+support structure was summarized, and the main design points and optimization ideas for the small high-rise residential development project were summarized, which can give certain inspiration and reference to similar engineering designs.
Keywords:frame+support structure; interlayer isolation structure; metro depot upper-cover residential development; structural system selection and optimization; buckling-restrained brace
