Abstract： In recent years， natural disasters occur frequently， and water damage accidents of bridges in mountain areas occur from time to time. The improvement of erosion performance of piers of river-wading bridges in mountain areas is gradually becoming a research hotspot. This paper summarizes the research status of impact-wear failure mechanism and protective measures of river-wading bridge piers in mountain area， and makes a numerical simulation analysis on the protective effect of a new protective measure， in order to provide reference for dealing with the problem of impact-wear damage of bridge structure.

Keywords： mountain area; bridge; protective equipment; concrete; impact effect
