| Abstract | A theoretical analysis based on a pseudo-three-phase media is presented, and the instability of a slope causing the debris flow is studied. The occurrence of fractures (or water films) in saturated soils in two cases is analyzed. The first case is that the water is forced to percolate through the soil upwards. A perturbation method is used in this case to obtain an approximate solution to explain the formation mechanism of cracks. The second case is about the cracks in liquefied soils. Numerical analysis and theoretical analysis are processed for this case. The formation of fractures in saturated grain accumulation under gravity is due to the blocking by redeposit of finer grains. The formation of fractures presents a sliding surface for landslides and debris flow. |
