Summary of research on evaluation of local scour around bridge pier

Abstract

In recent years, bridge disasters caused by scour have occurred frequently; hence, scour has become one of the most important factors that threatens the safety of wading bridges. Although the research on the local scour around bridge pier has been carried out for many years, there are few research results on the evaluation of scour hazard of built bridge piers and that of unbuilt bridge piers. On the basis of previous research results at home and abroad, this paper systematically analyzes the research results related to the evaluation of local scour of bridge piers in recent decades, including the prediction of scour pit depth, the risk assessment of local scour failure and the prediction of scour depth based on risk theory. In this paper, the trend of local scour evaluation of bridge piers is also discussed.
