Shear wave velocity of soil layer is a key parameter in the numerical simulation model of ground motion for various sites. For three-dimensional model, the cost of direct measurement of shear wave velocity is high. It is a common method to estimate the shear wave velocity based on the depth shear wave velocity empirical relationship. Based on the analysis of the empirical relationship between depth and shear wave velocity of various soil layers in Yuxi area, it is found that for the soil layer with obvious particle characteristics, the shear wave velocity has a significant positive correlation with particle size, and a significant negative correlation with particle roundness. The larger the water flow is, the faster the flow velocity is, the larger the sediment particles can be transported, and the smaller the particles can be transported in the water flow. The results show that the wave velocity of sediment layer is lower when the distance of transport is longer, and the wave velocity of sediment layer is higher when the distance of transport is shorter. In the field drilling data of Yuxi area, there is a significant negative correlation between void ratio and shear wave velocity, which can be further adjusted and modified by using the empirical formula of depth shear wave velocity of soil layer in Yuxi area. However, the specific gravity of soil particles has no obvious effect on its stiffness and shear wave velocity, and the specific reasons need to be further studied.
