Embodiment Construction
[0035] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. The specific embodiments described here are only used to explain the present invention, not to limit the invention.
[0036] Such as figure 1 As shown, a light-weight evaluation method for bridge bearing capacity based on impact load in this embodiment, the specific steps are as follows:
[0037] S1. Determine the magnitude of the impact load on the bridge and the location of the impact load loading point:
[0038] Formulate the bridge impact load test plan according to the bridge design data and the current load test specifications, and calculate the test efficiency coefficient of the section through theoretical calculation, and the test efficiency coefficient η d =s d / s, where η d is the load efficiency coefficient of deflection under impact load, s d is the maximum d...
