Abstract
In order to reveal the stress law of rigid suspension stiffened continuous steel truss bridge under highway and crowd loads, a highway rail bridge is taken as the supporting project, and the load test method is used to verify it. Firstly, the completed bridge state (the dead load of the lower track) is simulated by laying water bags on the lower deck, which solves the problem of asynchronous construction of highway and track. Then, the stress, deformation results and change rules of this kind of bridge under the test load are summarized by simulating the load action of highway and crowd through the loading vehicle, which can provide a reference for the load test of similar bridges.
