摘　　要：近年来自然灾害频发,山区桥梁水毁事故时有发生,针对山区涉河桥梁墩柱冲磨性能的提升正逐渐成为研究热点。该文综述山区涉河桥梁墩柱冲磨破坏机理及防护措施研究现状,并针对一种新型防护措施的防护效果进行数值模拟分析,以期为应对桥梁结构冲磨破坏问题提供参考。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.
