Abstract

Concrete structures in a sandstorm environment suffer from sandstorm erosion for a long time, which reduces the durability of concrete buildings, and then threatens the safety of buildings. Therefore, it is of great practical significance to study the aeolian sand load under the aeolian sand environment. In this paper, by numerical simulation of the sand load on the surface of bridge and simulation test of the sand load on the surface of the concrete in the sand environment, the variation law of the sand load under different sand parameters is studied. Through comparative analysis, it is concluded that the variation law of aeolian sand load in numerical simulation and test tends to be consistent with the variation of aeolian sand velocity and sand content ratio.
