摘　　要：对于隧道管片而言,管片接头部位的力学性能是影响整环衬砌结构承载力的重要因素之一。目前,在对管片进行研究时通常进行了不同程度的简化,但管片与管片之间相互影响,整环衬砌结构实际工作状态存在差异。文章通过建立有限元模型,研究不同简化及整环衬砌结构的管片接头在弹性阶段的力学性能。For tunnel segments, the mechanical properties of segment joints are one of the important factors affecting the bearing capacity of the whole ring lining structure. At present, the research on segments is usually simplified in different degrees, but the interaction between segments and the actual working state of the whole ring lining structure are different. By establishing a finite element model, this paper studies the mechanical properties of segment joints with different simplified and integral ring lining structures in elastic stage.
