摘要
本文以南通地铁环西文化广场站1号,2号线圆形无柱换乘枢纽设计为工程背景,采用不同有限元软件建立计算模型,进行施工期和运营期多种计算工况的内力对比分析及配筋验算,结论表明顶板密肋楼盖体系方案满足承载力及规范要求,整体挠度变形处于常规可控范围,确保了工程的经济性与合理性,本文研究结论对类似工程有借鉴作用。
This paper takes the design of circular column-free transfer hub of line 1 and line 2 of huanxi culture square station of Nantong Subway as the engineering background.Different finite element software was used to establish the calculation model,and the internal force comparison analysis and reinforcement check calculation are carried out in various calculation conditions during construction and operation period.The results show that the scheme of roof slab with Multi-ribbed floor system meets the requirements of bearing capacity and specification,and the deformation of the whole deflection is in the conventional controllable range,the economy and rationality of the project is ensured.The conclusions of this paper can be used for reference in similar projects.
