摘要
本工程位于杭州奥体博览城网球中心东侧,作为平时网球运动使用,屋面西侧利用桥墩设置滑动支座与市政桥相连。地下共二层,地上一层,地下室埋深10m,抗浮问题十分突出。主体采用钢筋混凝土框架结构,地下室东侧设置了高度约10m的悬臂挡土墙。比赛场地大空间区域屋盖采用跨度为40m的重型钢桁架+现浇混凝土板组合楼盖结构,桁架顶部覆土厚度约为1m。基础采用桩基承台+防水板的形式,比赛场地底板范围满布抗拔桩解决抗浮问题。
This project is located on the east side of the Tennis Center of Hangzhou Olympic Sports Expo City.It is used for daily tennis sports.The west side of the roof is connected with the municipal bridge by the sliding bearing set on the pier.There are two floors underground,one above ground,and the basement is buried 10 m deep,so the anti-floating problem is very prominent.The main body adopts a reinforced concrete frame structure,and a cantilever retaining wall with a height of about 10 m is set on the east side of the basement.The roof of the large space area of the competition field adopts a 40 m span of heavy steel truss+cast-in-place concrete slab composite floor structure,and the thickness of the top of the truss is about 1 m.The foundation adopts the form of pile cap+waterproof board,and the floor area of the competition field is covered with uplift piles to solve the problem of anti-floating.
