悬臂施工菱形挂篮行走安全分析研究

摘要

In the sea-crossing,ditch-crossing and urban-bridge construction,as cantilever con-struction technology is more and more widely applied,cradle construction safety in the cantilever con-struction process becomes an important research problem.In order to providing guiding significant advice and experience for similar bridges,we conduct an research and analysis on the force state and the ability of against overturning during cradle walking,at the same time,discussing the safety performance to en-sure the smooth progress of the construction process.%在跨海、跨沟渠及城市桥梁建设中，悬臂施工工艺应用越来越广泛，挂篮施工安全成为悬臂施工过程中重要的研究问题，对挂篮行走过程受力状态及抗倾覆能力进行研究分析，探讨挂篮在行走过程中的安全性能，保证施工过程的顺利进行，为同类桥梁施工提供具有指导意义的建议和经验。
