| 摘 要： | 依照千斤顶斜拉扣挂悬拼架设钢管混凝土拱桥的施工工艺，采用力矩平衡原理推导出扣索索力表达式，并考虑二阶效应分析了预抬高量与扣索变形之间的关系．最后，以广西邕宁邕江大桥为例，分析预抬高量的二阶效应，从而可以得到更精确的预抬高量分析数据，供工程设计及施工人员参考．

| Abstract: | According to the construction procedure of cantilever assembling concrete- filled steel arch bridge by cable- stayed through hoisting jack,adopting equilibrium principle of bending moment,concluded the expression of cable- stayed force. Studied the relation of deformed shape of cable- stayed and pre- raised height considering two order effect. An example showed this method is more accurate,the conclusion of this paper has reference value for engineering design and some builders. |
