摘要: 項目為地鐵車輛段的上蓋物業(yè),蓋下為已投入使用的地鐵車輛段,蓋上擬建多層住宅及幼兒園建筑. 通過方案論證與設(shè)計優(yōu)化等手段,最終采用了地鐵車輛段頂層作為蓋上結(jié)構(gòu)轉(zhuǎn)換層的設(shè)計方案,車輛段頂層框架梁采用點位連接上反組合梁的方式進(jìn)行加固. 此方案減少了結(jié)構(gòu)的抗震不規(guī)則性,提升了整體結(jié)構(gòu)的抗震性能,使得車輛段頂蓋層的結(jié)構(gòu)承載力得到充分的發(fā)揮,體現(xiàn)了綠色、環(huán)保的設(shè)計理念,并大幅減少了蓋上打鑿及植筋量,滿足了車輛段的保護(hù)原則,充分體現(xiàn)了對 TOD 項目結(jié)構(gòu)特點和技術(shù)難點的考慮,滿足安全、合理、經(jīng)濟(jì)的目標(biāo)要求.

Abstract:The project covers the property on the top of the subway depot, the subway depot that has been put into use under thecover, and the multi-storey residential and kindergarten buildings would be built on the top. By means of scheme demonstrationand design optimization, the top floor of the subway depot was finally adopted as the design scheme to be the structural transferlayer. The frame beam of the top floor of the subway depot was reinforced by the way of connecting the upper inverse compositebeam at the point position. This scheme reduces the seismic irregularity of the structure, improves the seismic performance of thewhole structure, gives full play to the structural bearing capacity of the top floor subway depot, embodies the green andenvironmental protection design concept, and greatly reduces the cover chiseling and amount of planting reinforcement, whichmeets the protection principle of subway depot and fully reflects the consideration of the structural characteristics and technicaldifficulties of the TOD project. This scheme meet the safety, reasonable, economic objectives.
Keywords:upper cover of subway; TOD; strengthening and reconstruction; point connection; composite beam
