连续梁拱组合结构柔性吊杆张拉力的确定

Determination of stretching force of flexible suspension rod in continuous beam arch combination structure

连续梁拱组合结构跨越能力大、建筑高度低、造型轻盈、线条流畅,是一种很有发展前途的结构型式。本文结合一座目前国内最大跨度的下承式梁拱组合双线铁路桥,介绍连续梁拱组合结构的特点以及确定成桥阶段柔性吊杆张拉力的方法。

The continuous beam arch combination structure has large span capacity, low building height, light graceful shape and smooth lines, and it is a structure type with development prospect. In combination with under-supported beam arch combination double-line railway bridge with the largest span domestically in our county, the characteristics of the beam arch combination structure and determination of the method for stretching force of flexible suspension rod in bridge formation were introduced in this paper
