摘要]周口市体育场主体结构采用钢筋混凝土框架结构,屋面钢结构罩棚采用空间网壳结构。体育场罩棚沿东、西两侧对称布置。罩棚中部支承在24根框架柱之上,两端分别通过12个支座支承于网架基础。工程罩棚基础采用桩筏基础,使用了多种桩型,其中钻孔灌注桩承受竖向荷载和横向水平荷载,斜向桩承受纵向水平荷载,基础四周采用水泥搅拌桩进行土体加固。本罩棚基础的设计较好地解决了基础变形及抗水平力的问题,可为类似工程提拱一定参考。

Abstract: The main structure of  Zhoukou Stadium is reinforced concrete frame structure and the steel canopy roof adopts spatial reticulated shell structure. The east and west canopys of the Stadium are symmetrical. The middle of the canopy is supported on 24 frame columns and both ends of the canopy are supported on reticulated shell foundation by 12 supporting points. Piled raft foundation was adopted and a variety of pile types were used in the project. The cast-in-situ piles bear vertical loads and horizontal loads in width direction, while inclined piles bear vertical horizontal loads in length direction. Soil around the foundation was reinforced by cement mixing piles. Foundation design of the canopy solves the problems of foundation deformation and horizontal force resistance, providing reference for the similar projects.

Keywords: Zhoukou Stadium; canopy; pile foundation
