The scouring effect is a crucial factor affecting the stability of the bridge foundation. Many engineering methods have been developed to reduce the impact of local scour on bridge structures. Among the commonly used protection methods, each method has its limitations and advantages. In this paper, passive method, active method and combination method are used to describe the effects of riprap, collars, slot, sacrificial pile, and vanes methods on the erosion protection effect. The overall judgment of each method is made through the analysis of the factors that may affect the efficiency of protection and the possible shortcomings in the use of protection methods. Then, the inference of device size is derived by combining the various scenarios of the method, so as to help the protection efficiency of the protection method reach the optimal state. Finally, the future development trend and application prospect of the protection method were prospected.
