摘　　要：盖挖逆作法施工地下车站结构过程中,墙板节点处的逆作施工缝是质量控制的关键点,也是侧墙渗漏水控制的重要环节。侧墙逆作施工缝通常留置成内高外低的斜面,以保证后续混凝土浇筑的密实性。逆作施工缝的具体留置方法多种多样,以北京城市副中心站综合交通枢纽工程为背景,研究侧墙逆作施工缝的留置方法,分析不同方法留置的逆作施工缝的优缺点。In the process of construction of underground station structure by reverse excavation method,the construction joint at the joint of wall panel is the key point of quality control and the important link of water leakage control of side wall.The construction joint of the side wall is often retained into a slope of high inside and low outside to ensure the density of the subsequent concrete pouring.There are many kinds of specific retention methods for reverse construction joint.Taking the integrated transportation hub project of Beijing City Sub-central Station as the background,this paper studies the methods of reverse construction joint on side wall,analyzes the advantages and disadvantages of different methods of reverse construction joint.
