摘要
随着我国桥梁建设的发展,悬臂浇筑工艺在大跨径预应力混凝土桥梁施工中广泛应用.本文重点研究挂篮行走过程实际受力状态,对挂篮各构件进行力学分析研究,对挂篮行走过程抗倾覆能力进行分析,探讨挂篮在行走中的安全性能,保证了施工过程的顺利进行,也为同类问题的研究分析提供参考经验.
With the development of bridge construction in our country, the cantilever technology in the construction of long-span prestressed concrete bridge is widely used. Focuses on hanging basket walking process actual stress state, mechanics research of hanging basket each component is analyzed, and ability to resist overturning process of hanging basket walking is analyzed. The safety performance of the hanging basket in walking is discussed to ensure the smooth progress of the construction process. The study provides reference for research and analysis of similar problems
