摘要
为研究矩形装配式地铁车站力学性能,聚焦深圳地铁五期项目中研发并应用的矩形全预制装配式车站结构方案,结合采用干式连接的全预制装配式结构方案的演化过程,详细介绍矩形结构方案的断面设计方案、结构分块及接头、梁柱内支撑体系和静动力力学特性等多个关键方面。矩形装配式车站结构方案可灵活适应不同站台宽度要求,采用通用可调模具有效提高了矩形结构方案构件通用性。同时,矩形结构可适用于三层两跨或两层三跨等不同型式车站的结构拓展。此外,通过足尺接头试验验证矩形装配式车站接头的抗弯承载性能,验证已有接头研究的理论计算方法在接头构造尺寸变化条件下的适用性。研究成果旨在为后续装配式结构设计与工程应用提供经验与参考。
This study focuses on a rectangular prefabricated station structure scheme developed and applied for the first time to the Shenzhen Phase V Project.Combined with the evolution process of the prefabricated structure scheme with dry connections,this paper introduces in detail the section design scheme of the rectangular structure scheme,structural partitioning and joint,bracing system of the beam-column,and static and dynamic performances.The rectangular prefabricated station structure scheme can be applied to different station width requirements,and an adjustable template is used to effectively improve the universality of the rectangular-structure components.Simultaneously,the rectangular structure can be expanded to accommodate different types of stations,such as three-layer two-span or two-layer three-span.Additionally,the bending bearing capacity of a rectangular assembled station joint was verified by a full-scale joint test,and the adaptability of the theoretical calculation method of the existing joint research to structural size changes was verified.The results of this study are intended to provide a reference and experience for subsequent prefabricated structure designs and engineering applications.
