Cable stayed bridge for test, and mounting method

The invention relates to the technical field of bridge tests, and especially relates to a cable stayed bridge for tests, and a mounting method. The cable stayed bridge comprises a horizontal main beam, a vertical shear wall and multiple inclined stay cables. Two ends of each inclined stay cable are fixedly anchored to the main beam and the shear wall. Multiple embedded parts are pre-embedded inside the main beam at certain intervals. Each embedded part is detachably connected to a connection plate. The connection plates are fixedly anchored to the inclined stay cables. The test scale, the loading difficulty and the test cost are effectively reduced, the reduced scale proportion of a model can be increased, the bridge is convenient to dismount and assemble, and cable forces can be leveled during a test. During a mounting process, people do not need to damage the main beam structure, the inclined stay cables are effectively preventing from crossing pre-stress pipelines inside the main beam, the overall force bearing of the main beam and the force bearing paths of the inclined stay cables will not be changed, the force bearing performance of the main beam and the inclined stay cables can be truly simulated, and the force bearing performance and the limit force resistance of the inclined stay cables and the main beam after the main beam breaks and stays in a force bearing state can be accurately simulated.
