摘　　要：基于UHPC连接的装配式墙体是一种用于地下装配式结构中采用特殊连接构造的新型结构形式。作为一种新型连接节点,掌握其结构性能对设计和应用有着重要的指导意义。结合实际工程,本文对2m高度的装配式墙体和现浇墙体进行了对比试验研究,考察了两种墙体在悬臂加载工况下结构的承载能力和变形能力,研究了连接节点的工作性能和安全性能,提出了针对该连接节点的计算方法,为地下装配式结构的工程设计和应用提供了参考。The fabricated wall based on UHPC connection is a new type of structure that adopts special connection structure in underground fabricated structure.As a new type of connection node,mastering its structural performance has important guiding significance for design and application.In combination with actual engineering,this paper conducted a comparative test study on a 2 m height fabricated wall and a cast-in-situ wall.The load-bearing capacity and deformation capacity of the two types of walls under cantilever loading conditions were investigated,and the work performance and safety performance of connecting nodes was studied.A calculation method for the connection node was proposed,which provided a reference for the engineering design and application of underground assembled structures.
