摘要: 汕頭亞青會(huì)場館項(xiàng)目(一期)包括一座 2.2 萬人體育場、一座 8 000 人體育館、一座會(huì)議中心、一座訓(xùn)練場.該場地為吹填淤泥成形,土體飽和,以流塑狀為主,無法滿足建筑功能及施工設(shè)備行走,并且存在不同沉降、不同承載力、不同建設(shè)時(shí)序等需求. 通過真空預(yù)壓、水泥攪拌樁和高壓旋噴樁進(jìn)行地基處理,取得了良好的固結(jié)效果,提高了地基承載力. 體育場和體育館均采用了屈曲約束支撐進(jìn)行減震設(shè)計(jì),分析結(jié)果表明:屈曲約束支撐在小震作用下彈性不屈服,可以為結(jié)構(gòu)提供抗側(cè)剛度,中震作用下屈服,可以發(fā)揮耗能減震作用,大震作用下出鉸充分,耗能減震效果明顯,說明屈曲約束支撐適合在高烈度地區(qū)采用.

Abstract: The venue project of Shantou Asian Youth Club Stadium Project ( phase I) includes a stadium for 22 000people, a gym for 8 000 people, a conference center, a training ground. The site is formed by blowing and filling silt, thesoil is saturated, and it is mainly in the form of fluid plastic, which cannot meet the needs of building functions andconstruction equipment walking, and there are different settlements, different bearing capacities and different constructionsequences. Through vacuum preloading, cement mixing piles and high-pressure rotary jetting piles for foundation treatment,a good consolidation effect was achieved and the bearing capacity of the foundation was improved. Both the stadium and thegymnasium use buckling restrained brace for shock absorption design. The analysis results show that the buckling restrainedbrace does not yield elastically under the action of frequent earthquakes, which can provide lateral stiffness for thestructure, yield under the action of midium earthquakes, and can exert energy consumption and shock absorption. Underthe action of rare earthquake, the hinge is sufficient, and the energy consumption and shock absorption effect is obvious,indicating that the buckling restrained brace is suitable for high-intensity areas.
