Example Embodiment
[0044] The present invention will be described in further detail below through specific examples. The following examples are only descriptive and not restrictive, and cannot limit the protection scope of the present invention.
[0045] A method for quickly assessing the bearing capacity of a bridge based on a moving load test. This embodiment takes a simply supported slab girder bridge as an example. The steps of the method are:
[0046] ⑴Determine the test efficiency, loading vehicle and measuring point layout:
[0047] According to the bridge design data and the current specifications, the mobile load test plan is formulated, the test efficiency is calculated, and the loading vehicle working conditions and measuring point layout are determined.
[0048] The simply supported slab girder bridge adopts a pre-tensioned prestressed hollow slab girder structure with a span of 13.8 meters. The full bridge has 11 slab girder, followed by 1#梁2, 2#梁3, 3#梁4, 4#梁5, 5#梁6, 6#梁7, 7#梁9, 8#梁10, 9#梁1...
