Research on coordinate calculation method of curve bridge piers and abutments center
摘要
Abstract
The coordinate of curve bridge piers and abutments center is the most important lofting data of bridge enginee⁃ring surveying. The commonly⁃used calculation method is the traverse method,but its calculation steps are tedious. According to the analysis of the relation between pier and abutment center coordinate and line center coordinate,and the calculation thought of ″method of deflection distance″ is put forward,in which the coordinate of the central line point is calculated according to the central line mileage,and on this basis,the coordinate is calculated according to the deflection distance from the normal direc⁃tion of the point towards outward moving. The method is compared with the traverse method in combination with the production practical case calculation. The results show that the ″method of deflection distance″ has clear geometric relation and easy calcula⁃tion formula,is easy to use in computer or programmable calculator for data processing,and can greatly reduce the difficulty of the coordinate calculation of the curve bridge pier and abutment center. It is worth advocating and promoting.关键词
