Constitutive relation description method for sand gravel soil in piping erosion
The invention discloses a constitutive relation description method for sand gravel soil in piping erosion. By means of the constitutive relation description method, a stress-strain relation of the soil mass during the piping erosion process and after erosion can be described in a quantitative manner, and the method is used for dynamically simulating piping erosion under the action of the seepage effect of a dam and analyzing the influence of piping erosion on the dam seepage and stress deformation as well as safety. By means of the method, the particle loss amount serves as an independent variable, the intensity and deformation parameters of a constitutive model serve as dependent variables, and the stress deformation of the sand gravel soil according to the loss amounts of particles of different sizes is simulated by establishing a relation of the model parameters and the independent variable.
