Abstract:In order to solve the problem of the shape measurement of arch ring for the evaluation of in-service arch bridge,a new method is presented that measures the arch ring using a reflectorless total station on the side of the arch bridge and the detail operations are given.The main measurement errors of X and Z coordinates are analyzed and the formulas for mean square errors of X and Z coordinates are derived according to the error propagation law.The measurement accuracy of the new method is verified by simula...
Keywords:reflectorless total station  arch bridge  measurement of arch ring  accuracy analysis
