［摘要］對2023年亞洲杯足球賽開、閉幕賽事場地北京工人體育場的結(jié)構(gòu)改造設(shè)計(jì)方案和關(guān)鍵技術(shù)進(jìn)行了介紹。由于抗震設(shè)防標(biāo)準(zhǔn)難以滿足、原結(jié)構(gòu)安全性能低、基礎(chǔ)及外圍框架加固代價(jià)高及外立面與初始設(shè)計(jì)外觀差別大等問題，最終選擇了復(fù)建方案。通過采用大跨屋蓋結(jié)構(gòu)減隔震設(shè)計(jì)、鋼結(jié)構(gòu)直接分析法設(shè)計(jì)、考慮設(shè)計(jì)-施工全過程的結(jié)構(gòu)優(yōu)化設(shè)計(jì)、新型加勁肋增強(qiáng)高瘦型箱形截面鋼構(gòu)件腹板局部穩(wěn)定性和超長混凝土結(jié)構(gòu)新型誘導(dǎo)縫等若干關(guān)鍵技術(shù)，達(dá)到了體育場設(shè)計(jì)安全、優(yōu)雅、適用、經(jīng)濟(jì)的目的。

Abstract: The structural reconstruction design schemes and key technologies of Beijing Workers Stadium, the opening and closing venue of the 2023 Asian Cup, were introduced. Due to the difficulty of meeting the seismic fortification standards, the low safety performance of the original structure, the high cost of reinforcement of the foundation and the outer frame, and the large difference between the exterior facade and the original design, the reconstruction plan was finally selected. The key technologies including seismic absorption and isolation of large span canopy, direct analysis method of steel structure, structural optimization considering whole process from design stage to construction stage, new stiffeners enhance local stability of webs of tall and thin box section steel members and new type of induced joints in super-long concrete structures were adopted to ensure that the stadium design achieves the goals of safety, elegance, comfortability and economy.
Keywords:Beijing Workers Stadium； structural reconstruction； steel structure canopy； seismic absorption and isolation； direct analysis method； local stability
