Static and Dynamic Loading Tests for Mixed Passenger and Freight Railway Double-track Super Large Bridge with Speed of 200 km/h
To prove the correction of the design theory, check the quality of the overall structure and evaluate the safety of high speed traffic systems, and thus to provide scientific basis of engineering acceptance, the static and dynamic loading tests are carried out on the Lu-Shui double track super large bridge with the speed of over 200km/h. The tests include the bridges displacement, main elements stress, natural frequency and impact coefficient, et al. Comparison of the tested data and the calculated results obtained from ANSYS finite element model of space entity is further made, and the results show that the design theory of the bridge is correct and the bridges working status satisfies the designing requirement. The tests provide essential technical parameters for safe operation of the bridge in future, and it also could be considered as important technical information for researching the static and dynamic characteristics of the longer and more complicated high speed railway bridge structures.
