摘　　要：木材榫卯结构作为传统结构形式之一,相比于混凝土结构具有较强的破坏延展性,这与榫卯节点处的界面力学机制密切相关。对木材榫卯节点界面力学进行诠释,对于提高木结构古建筑修复与保护技术、开发新型木结构具有重要意义。文中概述木材榫卯节点界面力学研究现状,主要包括榫卯节点界面力学的影响因素,理论分析与数值模型,以及考虑界面力学的榫卯节点增强技术;重点梳理分析榫卯节点界面力学作用机制的研究进展,并展望了未来研究的热点与发展方向,旨在深入理解榫卯节点的力学行为,为提高木制品与木结构的安全性和耐久性提供科学依据。Wooden mortise-and-tenon joints,as a traditional structural form,demonstrate greater damage tolerance than concrete structures,primarily due to the interfacial mechanical mechanisms at the joint connections.Understanding these interfacial mechanics is crucial for enhancing the conservation and restoration of historic wooden buildings and developing new-brand wood structures.This paper reviews the current research on the interfacial mechanics of wooden mortise-and-tenon joints,covering influencing factors,theoretical analyses and numerical models,and discusses the reinforcement techniques that consider interfacial mechanics.It highlights the research progress made in the working mechanisms of the interfacial mechanics at the joints and describes hotspots and directions of future research.It is aimed to deepen the understanding of the mechanical behavior of mortise-and-tenon joints and provide a scientific basis for improving the safety and durability of wood structures and products.
