【摘要】 地铁车站设计中,柱网的布置对整个车站的主体结构受力及车站内部设备、机房等平面布置具有重要影响。由于地铁车站结构力学性态复杂,地下结构的计算目前停留在软件计算阶段,尚未有关于柱轴力的理论解析式,但软件计算结果难以明确荷载传递方式、分析影响柱轴力的因素。本文基于对框架结构的力学解析,从荷载传递的角度出发,分析了影响柱轴力的因素及其影响程度,得到了柱轴力的简易解析式。其分析结论明确了荷载传递方式,对于地铁车站的设计具有重要的理论指导意义和实际使用价值。更多还原

【Abstract】 In metro station design,the column arrangement has great influence on the stress of main structure and the layout of equipments and machine rooms in station. However,due to the complex mechanical behavior of the metro station structure,the calculation of underground structure remains in the stage of software calculation,which is difficult to clarify load transfer mechanism and analyze the influencing factors of column axial force,and there is no theoretical analytic expression at present. This paper based on mechanical analysis of framework structure,from the point view of load transfer,analyzes the factors affecting the column axial force and their impact,and gains simple theory analytic expressions of column axial force. The paper’s conclusions clarify the load transfer mechanism and have great theoretical guiding meaning and practical application value to design of metro station.更多还原
