This paper introduces a new failure mode pattern of soil slope – the logarithmic spiral slippery fracture. A mathematical model for the logarithmic spiral slippery fracture is established, taking the anti-shear function of the soil-nailing into consideration. The shear of soil-nailing, axial force, and the safety coefficients based on the limiting equilibrium method are derived, leading to an accurate stability analysis of the strengthening of soil slope. A case study shows that the anti-shear function of the soil-nailing can be significant and should not be ignored in engineering design.

Level Monitoring

The developed groundwater pipe network drainage system in the gravel soil slope has a significant impact to its stability. Considering the underground water level monitoring result, this paper simulates the xikengkou slope after the excavation and rainfall conditions based on fluid-solid coupling. The result presents that excavation at toe of slope damaged the groundwater discharge path. In the rainfall condition, the groundwater level increases significantly, which leads displacement occurring within the gravel soil slope. On the other hand, the displacement makes the drainage system be further destroyed and the permeability coefficient continues decreasing. Finally, the high water table leads the slope stability decreasing considerably, even to instability.
