2) arch axis linear control
拱轴线形
1.
Non-bracket and Cable erection is the main erecting arch ribs method of a long span concrete-filled steel-tube(CFST) arch bridge recently,but it requires to adjust the cable force over and over again,which increases the degree of construction difficulty and arch axis linear control trouble,delays the project limit time.
无支架缆索吊装法是目前大跨径钢管混凝土拱桥拱肋节段吊装的主要施工方法,此方法在施工过程中须反复调整扣索索力,施工难度大,拱轴线形控制繁琐,工期长。
3) arch axis variation
拱轴线形偏差
1.
However,till now in our country ,there is no design and construction code for concrete-filled steel-tube arch bridge,specification against arch axis variation is also established on previous bridge-constructing performances.
近年来,随着钢管混凝土拱桥的修建在我国兴起,钢管混凝土拱桥跨径不断增大,对拱轴线形的控制难度也越来越大,而迄今为止我国还没有专门的钢管混凝土拱桥设计与施工规范,对于拱轴线形偏差的规定也是建立在以往建桥实绩的基础上提出的,不可避免,一些线形指标会存在不合理的内容,因此又必要对大跨度钢管混凝土拱桥施工过程中出现的拱轴线形偏差进行分析。
4) configuration change of the arch
拱圈的线形变化
5) arch axis
拱轴线
1.
Continuum topology optimization method for arch axis design of arciform aqueducts;
结构拓扑优化方法在拱式渡槽拱轴线设计中的应用
2.
Optimization of spline function curve used as arch axis based on gen etic algorithm
遗传算法下样条函数曲线作为拱轴线的优化
3.
The effects of deformation and internal forces produced by transverse bias of arch axis are analyzed by simulative computing.
针对某上承式钢筋砼箱板拱桥建成后的拱轴线与设计拱轴线发生横桥向偏离,通过计算仿真分析探讨拱轴线偏离对主拱内力和变形的影响,提出了几种改善主拱受力状态的措施,为同类拱桥的施工偏差和加固维修提供借鉴。
6) arch axes
拱轴线
1.
Moreover, adjust of the arch axes of this kind of bridge is quite limited and no adjust for the structural figure and stress is available after construction.
该桥施工中的稳定问题十分关键，而且，这种拱桥的拱轴线在施工过程中的调整非常有限，成桥后结构的线形和应力也不能再作调整。
