某工程地下室停车塔库设计难点研究分析

Research and Analysis on the Difficulty of Design for a Basement Stereo Parking Tower

某工程地下室机械停车塔库,由于功能需要,其负1层及负2层顶板对应位置均须开大洞口,形成10.2m高的悬臂侧壁。根据工程特点,采取加悬臂式扶壁墙的方法。本文结合有限元分析方法,对扶壁墙、塔库区域负2层楼板、扶壁墙基础进行受力分析,并给出相应的设计结论以供类似工程参考。

A vechicle mechanical stereo tower always has big holes opened at the roof of the basement and sub-basement respectively due to requirements of traffic. A cantilever wall with the height of about 10.2 meters will be formed near the holes. And the retaining wall is without support from the horizontal floor. Thus more walls will be added. However,the normal design of retaining wall for such case is uneconomic and unsafe. In this paper,a new design with adding buttress walls has been conducted based on the structural stress analysis,in which,buttress walls,the foundation of buttress walls and the roof of sub-basement are all included,and for reference of similar projects.
