钢管柱与贝雷梁组合支架法施工研究

A Study on Steel Pipe Column and Bailey Beam Combined Bracket Method

钢管柱一贝雷梁组合现浇支架体系结构现越来越多地应用于连续梁桥施工,该方法以其满足施工结构净空需求,成本低廉,施工便捷等优点被工程技术人员所采用的,并迅速推广开来,但其结构的受力检算却缺少全面的建模和理论研究,本丈为了进一步规范贝雷支架的使用,提高其经济效益,建立在模型分析与理论结合的基础上,即采用电算与手算相结合的计算方式,对钢管柱一贝雷梁组合支架结构做出最优选择,使得施工更为高效,安全的进行。

The steel pipe column-Belle beam combined with cast-in-place bracket structure is now more and more applied to the construction of continuous beam bridge.This method is adopted and promoted quickly by engineers and technicians to meet the requirements of construction structure clearance,low cost and convenient construction,but the structural force calculation lacks comprehensive modeling and theoretical research.In order to further standardize the use of Bailey support and improve its economic benefits,this paper is based on the combination of model analysis and theory,that is,both computer calculation and hand calculation are used to make an optimal choice of support structure of steel tube column and Bailey beam,so that the construction is much more efficient and safer.
