In recent years, the economy of China is rapidly developed, and a large number of large bridges spanning the rivers of the great river, such as a Hongzhu Australian bridge, an east-sea bridge, a Hangzhou Bay bridge, a Lijiatuo bridge in Chongqing city, and the like, are built immediately. Most of the bridges across rivers adopt deep water pile group foundations, and the size and the water blocking area are large. The safety and stability of the bridge pile foundation in the complex water flow environment depend on the stress condition of the bridge pile foundation in the complex water area environment, and are also related to the reduction of the bearing capacity of the pile foundation caused by the shallow burying depth of the bridge pile foundation caused by water flow scouring. And a large number of investigation statistical results also show that one of the main causes of bridge damage is caused by the reduction of the embedded depth of the bridge pier due to the local scouring of the bridge pier foundation.
