摘要：
Technology on rating for operation performance of high-speed railway long span cable-stayed bridge was discussed based on the dynamic performance test practice and measured data of long span cable-stayed bridges used in high-speed railways in China in recent years. The main technical parameters to evaluate the operation performance of long span cable-stayed bridges of high-speed railways were proposed. For the long span cable-stayed bridge with the main span 430-630 m, a formula between the 1st vertical and lateral natural vibration frequency reference value of the beam with main truss span and width was proposed. The ratio 1/800 was advised as the reference value of main span ratio of deflection to span. The reference value of 1.0‰ or 1.5‰ was recommended for the vertical rotation angle at girder end in line with the difference of the bridge design live load. Suggestions on the test method of different rating parameters are proposed. Further accumulation and analysis are required on the measured data of the operation performance of long span cable-stayed bridge used in high-speed railways in China, so that the evaluation code for operation performance of long span cable-stayed bridge used in high-speed railways in China may be drafted. © 2018, Department of Journal of the China Railway Society.
