[摘要]周口市體育場(chǎng)主體結(jié)構(gòu)采用鋼筋混凝土框架結(jié)構(gòu),屋面鋼結(jié)構(gòu)罩棚采用空間網(wǎng)殼結(jié)構(gòu)。體育場(chǎng)罩棚沿東、西兩側(cè)對(duì)稱布置。罩棚中部支承在24根框架柱之上,兩端分別通過(guò)12個(gè)支座支承于網(wǎng)架基礎(chǔ)。工程罩棚基礎(chǔ)采用樁筏基礎(chǔ),使用了多種樁型,其中鉆孔灌注樁承受豎向荷載和橫向水平荷載,斜向樁承受縱向水平荷載,基礎(chǔ)四周采用水泥攪拌樁進(jìn)行土體加固。本罩棚基礎(chǔ)的設(shè)計(jì)較好地解決了基礎(chǔ)變形及抗水平力的問(wèn)題,可為類似工程提拱一定參考。

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
