摘要
上下锚箱定位技术保证了拱肋在施工中锚箱位置的准确性,确保了吊杆与张拉杆在一条直线上,为后期系杆拱桥吊杆安装及张拉创造了有利条件,保证了吊杆的位置及索力值符合设计要求。该文介绍的相关经验可供类似工程参考。
The upper and lower anchor box positioning technology guarantees the anchor box location accuracy in the construction of arch rib,ensures the steeve and tension rod in a straight line for creating the advantage conditions to install and tension the steeve of bowstring arched bridge later,and assures the steeve position and cable force value to satisfy the design requirement. The article introduces the relative experience for the similar projects.
