摘　　要：塔吊的安全性和稳定性决定着整个工程项目能否顺利进行。为了确保塔吊的安全,需要对塔吊附着节点的力学性能进行分析。本文以某工程项目为背景,用ABAQUS软件建立了内爬式塔吊附着节点的模型,分析了附着节点中牛腿部件的安全储备情况,改变附着墙体混凝土级别、墙厚和预埋件结构形式后附着墙体和预埋件的受力性能,为此类附着点的设计和施工提供了经验。The safety and stability of tower crane can decide the project can proceed Slnoothly or not. Stress analysis on tower crane attachment is necessary to ensure the safety of tower crane. This paper takes a project as a background, building the attachment model of inner climbing tower crane by ABAQUS. The security situation of bracket parts on attachlnent is analyzed. Mechanical properties of attachment wall and embedded part is also analyzed in condition of different grade of concrete,the thickness of the wall and embedded parts structure,providing experience for the design and construction in this kind of attachment.
