摘　　要：为解决现浇法站台板施工质量差、工期紧张、工序繁多等问题,提出一种以活性粉末混凝土(RPC)为材质的预制装配式站台板,重点研究站台板的拆分设计、接头连接、施工方法,采用数值模拟对站台板结构吊装及使用阶段的受力进行计算,验证结构体系和连接节点的合理性,并从技术和经济方面与常规的站台板进行对比分析。结果表明:1)站台板采用RPC混凝土,抗压、抗折强度高,可减小构件断面尺寸、减轻结构自重,站台板下墙体采用空腔结构,实现了构件轻量化。2)站台板不同模块化组合方案,适用于不同工法车站的圆柱和方柱;对于不同站台宽度采用模块化组合,构件规格少,通用性强。3)节点连接可靠,结构受力合理,各项应力变形指标小于规范限值,满足承载力及正常使用要求。4)基于构件分块及组合方案,提出安全且行之有效的的施工方法。5)装配式站台板有利于提高施工速度,保证施工质量,为实现轨道交通绿色全方位安全建造奠定了基础。The cast-in-place platform plate presents various disadvantages,such as poor construction quality,tight deadlines,and numerous construction processes.To address these challenges,a prefabricated assembly platform plate made of active powder concrete is proposed.The design of the disassembly process,node connections,and construction methods for this platform plate are thoroughly analyzed.Furthermore,numerical simulations are conducted to evaluate the structural forces during both the lifting and operational stages.Furthermore,the rationality of the structural system and connection nodes is verified,and a comparative analysis is conducted against a conventional platform plate in terms of technical and economic factors.The results reveal the following:(1)The platform plate is made of reactive powder concrete with high compressive and flexural strength that can reduce the cross-sectional size of components and the selfweight of the structure.Furthermore,cavity structures are incorporated in walls beneath the platform,achieving lightweight components.(2)Various modular combination schemes for platform plates are explored,tailored to accommodate cylindrical and square columns in stations constructed using different methods.A modular combination is adopted for different platform widths,with a lower number of component specifications and better universality.(3)Node connections are proven to be reliable,with reasonable structural stress distribution.Both stress and deformation indices remain within the specified limits,meeting the requirements for bearing capacity and normal application.(4)Safe and effective construction methods are proposed based on component partitioning and combination schemes.(5)The prefabricated platform plates significantly improve construction speed and quality,while laying the groundwork for sustainable,all-round safe construction of rail transit.
