1) pre-camber
预抬量
1.
The method is able to determine the cable-stayed force and pre-camber simultaneously.
扣索索力确定和标高预抬量计算是大跨度拱桥在采用无支架缆索吊装施工过程中的难点和核心问题,本文在原有的连续体弹性-刚性支承法的基础上,提出了改进的弹性-刚性支承法:即当前施工节段处的扣索模拟为刚性支承,对已施工节段的扣索模拟弹性结构,节段之间的连接考虑为转动弹簧。
2) preraised height
预抬高量
1.
Considering the second-order effect in analyzing temperature effect, the relationship between preraised height and the deformation of stay cables is obtained.
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;在分析温度效应时考虑二阶效应,导出了预抬高量与扣索变形之间的关系。
3) prearranged height
预抬高值
1.
The prearranged height calculations in control points of steel arch ribs during constructing a concrete-filled steel tubular arch bridge are divided into two parts: rigid body displacement and elastic deformation.
对钢管混凝土拱桥吊装施工拱肋控制点的预抬高值分两部分进行考虑:一部分由刚体位移引起,一部分为拱肋弹性变形产生,两部分之和为实际的预抬高值。
4) prearranged height
预抬高
5) pre-raising height for monitoring the main girder
主梁立模监控预抬值
1.
Determination of pre-raising height for monitoring the main girders with full-frame method;
满堂支架法施工中主梁立模监控预抬值的确定
