Abstract

The invention relates to a railway cable-stayed bridge test model. The railway cable-stayed bridge test model comprises a railway cable-stayed bridge body, rigid bridge connectors and a steel rail, wherein the steel rail is paved on the railway cable-stayed bridge body and used for a test car to run thereon. The railway cable-stayed bridge body is manufactured sectionally and are combined and assembled by the rigid bridge connectors. A test loading device used for simulating static and dynamic load of a cable-stayed bridge and a data acquiring device used for acquiring test data are mounted on the railway cable-stayed bridge body. The railway cable-stayed bridge test model simulates static and dynamic load on the cable-stayed bridge using the test loading device and acquires bridge test data under the action of the static and dynamic load by the data acquiring device in time. The railway cable-stayed bridge test model can simulate structural responses of the cable-stayed bridge under working conditions of different loads and provides reference test data for bridge structure design and long-term and effective operation of the cable-stayed bridge is ensured.

Description

technical field [0001] The invention relates to the technical field of bridge mechanics simulation test devices, in particular to a test model of a railway cable-stayed bridge. Background technique [0002] Cable-stayed bridge is a structural form widely used in bridge engineering. Under the new traffic situation, it is particularly important to ensure the long-term and effective operation of cable-stayed bridges, so it is necessary to conduct test experiments on cable-stayed bridges. [0003] However, on-site test experiments will affect traffic flow, and the cost is relatively high. Model test has become an indispensable means to solve new problems in the research and design of cable-stayed bridges, so a test model that can simulate cable-stayed bridges well is needed for research. However, the existing cable-stayed bridge models are all constructed by one-time integral pouring, which is very complicated, and most of the tests are carried out indoors, and the model needs...
