摘要
大底盘多塔结构的住宅小区,可以在建筑物之间的地面设置庭院、道路和绿化,地
下部分设计为地下车库,用以解决逐渐突出的绿化与停车的矛盾问题。地下车库作为建
筑物的附属建筑,已经成为必不可少的配套设施,但在地下车库设计过程中,由于车库
顶板结构形式和覆土厚度的差异,设计规范对消防车荷载的规定比较模糊,有必要进行
深入研究。
论文根据《建筑结构荷载规范》关于消防车荷载的相关规定,考虑等效均布荷载的
条件、最不利布置,进行理论计算,分析荷载与板跨、覆土厚度的关系,结合有限元分
析软件,研究了单、双向板在不同板跨及覆土厚度作用下的等效取值范围,得到不同工
况下消防车等效均布活荷载的合理取值。研究结果表明,现有荷载规范对地下车库消
防荷载的取值规定过于笼统,并且在跨度较小、覆土厚度较薄的情况下,板上等效均布
活荷载取值偏小。在足够覆土条件下,单、双向板的等效均布活荷载可按竖向轮压荷载
统一取值10KN / m2 。
根据《汽车库建筑设计规范》之相关规定,参照其他相关规范条文,考虑汽车运行
规律,对比常用柱网取值,通过理论计算,得到了柱网优化的建议参数。
以某工程实例为背景,对主次梁结构、反梁结构、井字梁结构、空心楼盖和无梁楼
盖等几种车库顶板结构方案的经济性能进行对比分析,讨论了各方案的优劣,并对组合
楼盖体系做了简要的介绍。

ABSTRACT
munities with multi-tower structure and enlarged base have already
became essential building facility. They take the advantage of the courtyards’ underground
parts to form a space, in where underground garage can be designed to solve the increasingly
prominent contradiction between greening and parking. However, during the design process,
because of the differences between the roof structure of garage and the thickness of covering
earth, as well as the vagueness in fire load description of our design specifications, it is
necessary to make an intensive of it.
In this paper, considering from relevant provisions of the fire load in “Loading code for
design of building structures”, and the fact of the equivalent uniform live load and its most
unfavorable arrangement, we can get the reasonable value of fire loading under different
conditions through the way of theoretical calculations, relationship analysis of load,
cross-board as we
