以圆形为特征的地下智能停车库在城市中日渐兴起,但其围护结构的计算方法及相关规范尚不成熟。本文以实际工程为背景,进行了基坑开挖阶段和正常使用阶段两种工况下的软件计算分析,并进行了抗震分析,然后以计算分析结果为依据,对两种常用的钻孔咬合灌注桩结构形式进行计算对比,选出最佳方案。提出在保证施工质量的前提下,采用钻孔咬合灌注桩的围护结构可作为结构主体的一部分用于永久性结构,为以后的类似圆形围护结构工程提供实用参考。
The underground smart parking garage with circular shape is rising in the city, but the calculation method and the related norms of its envelope are immature. Based on the actual project, the software calculation and analysis under two conditions of excavation and normal use are carried out, and the anti-seismic analysis is carried out. Based on the calculation and analysis, two kinds of commonly used drilling bite Pouring pile structure form contrast, choose the best plan. It is put forward that under the precondition of ensuring the construction quality, the retaining structure adopting bored piles can be used as a permanent structure as a part of the structure body, providing a practical reference for the subsequent similar circular retaining structure engineering.
