This paper is based on the former research taking the No.1 Tong-Lv Bridge as an example; the large universal finite element program Midas/Civil is adopted, a three-dimensional finite element model is established. The static performance, the comparative analysis of influence surfaces, the experimental study and the analysis of a local finite element model of the new style three-span continuous through type bow-string arch bridge is made. With these studies, this paper is aimed at revealing the performance of this kind of construction.

本文在前人研究的基础上，以通吕一号桥为背景，采用空间有限元法对结构形式新颖的三跨连续下承式系杆拱桥的静力性能、影响面比较分析、实桥荷载试验、局部节点分析等进行研究，旨在深入理解该结构形式桥梁的力学性能，为今后相同结构体系桥梁的结构分析提供可以参考的建议。

The structure internal forces were analyzed under different kinds of tension using a finite element computation model for the whole bridge with Midas software,and rational tension values and subsequence are finally calculated.

结合系杆拱桥的设计方案，对吊杆张拉力的控制进行分析计算，并利用Midas程序建立全桥的有限元分析模型，分析比较几种张拉情况下的结构内力变化情况，最终得出比较合理的张拉力取值及顺序，分析结果可为同类桥梁的设计与施工提供一定的参考。

The thrust of arch springing line during each phase is resist by corresponding tied bars. In a certain state, it is critical and important to make the correct value and reasonable time of pull of tied bars.

在某个特定状态下，合理确定系杆张拉力的大小和张拉时间成为施工控制的关键，在该桥控制过程中起着非常重要的作用。
