摘　　要：通过分析深圳某地铁车辆段大底盘上盖多塔结构设计过程,分别建立整体模型与分塔对称、不对称模型,并分析不同模型间楼层剪力的变化,通过对比地震剪力及实际配筋得出,转换层大部分位置的配筋值维持单塔的计算结果,单塔楼面梁的配筋值计算结果大部分大于多塔的计算结果。然后分析大底盘多塔结构温度应力的影响,得出在塔楼边界位置易出现应力集中现象,需要采取楼板加厚、双层双向配筋,并根据温度应力计算结果附加配筋等措施进行加强。Through the analysis of the design process of multi-level tower structure on the large foundation of a metro depot in Shenzhen,establishes the whole model and the symmetrical and asymmetric model of the tower structure respectively,and analyzes the change of floor shear force among different models.By comparing the seismic shear force and the actual reinforcement,it calculates the reinforcement value of larger parts of the transfer floor by maintaining the calculation result of single tower,and the reinforcement value of single tower floor beam,while most of them are larger than those of multi-level tower calculation.Secondly,it analyzes the influence of temperature stress of multi-level tower with large foundation.The phenomenon of stress concentration tends to appear at the boundary of the tower.Therefore,it is necessary to take measures such as thickening of floor and slab,double-layer bidirectional reinforcement,and additional reinforcement ribs in accordance with the calculation results of temperature stress.
