The Study on Precision Positioning of Cableway Pipe in Large-scale Cable-stayed Bridge

This paper presents the principle and method,which are combinded with the practice of modern large-scale cable-stayed bridge,about precision positioning of cable way pipe,a component of cable-stayed bridge,and analyses the accuracy and quality of psitioning for cableway pipe,pointing out the problematic areas that need improvement in design and structure in order to guarantee the quality of positioning.
