地下车库装配箱空心楼盖经济性分析初探

The Economic Analysis of the Hollow Floor of Assembly Box of the Underground Garage

本文针对普通地下车库展开普通梁板式楼盖和装配箱空心楼盖的经济性分析比较。在进行其经济性分析的过程中,选取了6种常用的地下车库跨度(8~13m),在附加荷载(1.0m覆土)下进行计算,得出两种楼盖在不同跨度下的用钢量。最后对各楼盖的用钢量节约程度进行比较分析,得出经济性分析结论。

Focusing on which kind of structure is more economical, the beam-and-slab floor and the hollow floor arecompared in this paper. In the process of its economic analysis, the 6 commonly-used underground garage span kinds areselected （8~13 m）, and the additional load calculation （with the soil depth of 1.0 m） is carried out so as to find out thedifferent steel quantities with different spans applied to the two kinds of buildings. In the end, the economical conclusion isdrawn by comparing the sparing degrees of steel consumption, and the economic analysis conclusion is obtained.
