| Abstract: | As for the mountain roads, the phenomenon of small bridges and culverts flood damage is very common, which often poses a serious threat to the subgrade stability and traffic safety. The flood damage genetic mechanism of small bridges and culverts is complex, and it is influenced by many factors. For the important fac- tor such as the inlet and outlet, the indoor fixed bed model test for the hydraulic characteristics is done, which can provide the basis for the prevention of small bridges and culverts flood damage. |
