Because of much influence factors, longer test period and differences of test method, it is not enough deeply for study of erosion mechanism of steel structure coating in sandstorm, especially the study for erosion of steel structure coating by sandstorm in the central and western regions of Inner Mongolia has not carried out. This paper analyzes and compares a variety of test methods, and carries out test verification, the results show that sediment flow injection methods is a better test methods to simulate erosion in sandstorm. The study will provide basis for revealing the erosion mechanism of steel-structure coating in sandstorm.
