贝雷架作为桥梁承重支架应用时的理论分析与实践应用研究

贝雷承重支架与贝雷架便桥在结构布置和受力状态上有较多不同，贝雷架设计与施工不能完全套用贝雷便桥的相关技术参数，因此有必要研究贝雷架作为承重支架时的力学参数和计算方法。根据既有贝雷便桥的容许承载能力计算理论，通过对贝雷架力学状态的进一步分析，提出了容许承载能力折减计算方法。同时根据贝雷支架的施工特点。指出了贝雷架作为承重支架应用时的荷载取值、纵横向布置方法和具体实践要点，形成了一套较为完善的贝雷支架应用理念，既保证了结构的安全，又节约了材料，对今后的施工有一定的指导意义。

Theoretical analysis and application about Bailey bearing frames in the bridge constructions

There are many differences in construction arrangement and loading conditions between Bailey bearing frame and Bailey bridge.Technical parameters about Bailey bridge can not be wholly applied in the design and construction for Bailey bearing frame.It is necessary for studying the mechanical state and calculation method about Bailey bearing frames.Based on the existing theory,the calculation methods for allowable bearing capacity of Bailey bridge are put forward through further studying the mechanical state ...
