Study on Spatial Distribution of Permeability Coefficients in Embankment Soils Based on Normal Information Diffusion
The permeability coefficient of embankment soil layer has significant spatial variability,and the spatial var-iability characterization of the permeability coefficient is the basis for studying its spatial distribution.Taking the Wuhan section of the Yangtze River embankment as an example,this paper collects 111 groups of measured data of loamy soil permeability coefficient of embankment body,introduces the normal information diffusion distribution to construct the permeability coefficient characterization model.The method of covariance matrix decomposition is used to establish the spatial distribution of the permeability coefficient of the simulated permeability coefficient of the random field.The results show that the loamy soil permeability coefficients of the five embankments have strong spatial variability,and the intro-duced normal information diffusion distribution model can effectively characterize the distribution of the permeability coef-ficients,and the permeability coefficient random field with normal information diffusion distribution can accurately repre-sent the spatial distribution of the permeability coefficients.
