Horizontal and vertical stress distribution of three numerical models: (a) stress distribution of the top part of the linear boundary model; (b) stress distribution of the bottom part of the linear boundary model; (c) stress distribution of the top part of the single-step boundary model; (d) stress distribution of the bottom part of the single-step boundary mode; (e) stress distribution of the top part of the multistep boundary mode; (f) stress distribution of the bottom part of the multistep boundary model.
