| Abstract: | 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. |
