Web8 Sep 2024 · Seepage theory mostly adopts the calculation method of uncoupled seepage and deformation, which fails to consider the hydromechanical coupling effect of unsaturated soil, so it cannot truly reflect the change in the seepage field under rainfall conditions. Web21 Jan 2024 · The unsaturated seepage theory is combined to study the changing mechanism in slope displacement and pore water pressure under different rainfall patterns. The influence of the accumulated pore water pressure and the displacement of the slope is analyzed with respect of the intermittent time.
