梁拱式组合结构在大跨度重载地埋泳池中的应用

Application of beam arch composite structure in large-span heavy-duty buried swimming pool

在大跨度重载地埋泳池结构工程中,作者比较了3种结构选型方案。受新型空腹式ASGRF桥结构体系的启发,采用型钢混凝土梁拱结构进行计算和设计,可以在不影响净高的条件下,实现全埋式地下泳池的建筑功能。在构造措施上对截面钢筋进行了深化排布,避免型钢、钢筋碰撞和浇筑困难。在底板处通过施加预压应力,对拱脚处的外推力进行了平衡。可为同类型大跨度地埋式结构的设计提供参考。

In a large-span heavy-duty buried swimming pool structure,the authors compared 3 structural options.Inspired by the ASGRF bridge system,section steel concrete beam arch structure is used inthe design,which can realize the building activities of the fully buried underground pool without affecting the net height.In consturct measures,the cross-sectional steel bars are placed to avoid the collision of section steel and steel bars and the difficulty of pouring concrete.By applying precompression stress at the base plate,the outwardforce at the arch foot is balanced.It can provide a reference for the design of the same type of large-span buried structure.
