Abstract：
The article takes the second unload platform responding to the ribbed floor of a waste transfer station as the research object, carrying out the research by the method combining damage investigation with loading testing. The three kinds of operation condition test adopting full garbage trucks shows that the vertical deformation of floor system is small while its stiffness is bigger. The main reason of causing surface damage are lacking structure measures such as the lack of effective connection between the deformation joints, and the lack of shear connection between surface and floor system. Based on it, the article puts forward to strengthening and reinforcing it should follow the guiding ideology: cutting off damage, local reinforcement, strengthening the interface and laying emphasis on construction.
