摘　　要：整体装配式地下车站叠合式墙板存在大面积预制混凝土板与现浇混凝土如何有机结合、解决现浇混凝土裂缝和墙体渗漏的问题,这与传统现浇混凝土施工工艺存在较大差异,其具体实施过程中将面临很多新的结构、材料和施工技术方面的问题。针对某城市轨道交通地铁车站建设的需要,基于现有大面积混凝土收缩裂缝和新老混凝土约束裂缝现状和控制技术研究成果,从结构设计、混凝土材料、施工技术三方面,探讨并提出了地下车站整体装配式叠合墙板裂缝控制的有效措施。The integrally assembled underground station laminated wall panel has the problems of how to organically combine the large area of precast concrete slab and cast-in-place concrete,and how to solve the problems of cast-in-place concrete cracks and wall leakage,which is different from the traditional cast-in-place concrete construction process.During its specific implementation process,it will face many new structural,material and construction technology issues.In view of the needs of the construction of a certain urban rail transit subway station,based on the existing large-area concrete shrinkage cracks and the new and old concrete restraint cracks status and control technology research results,from the three aspects of structural design,concrete materials,construction technology,the underground stations effective measures for crack control of integrally assembled laminated wall panels are discussed and put forward.
