Seismic Stability Analysis of Stabilizing Piles Reinforcement of Soil Slope Based on Spencer Method
Aiming at the problem of seismic stability analysis of slopes reinforced by stabilizing piles,based on pseudo-static analysis and the theory of limit equilibrium,the extended Spencer method for seismic stability analysis of slopes reinforced by stabilizing piles is proposed.Based on this method,the curve of pile shear force and slope safety factor is received,and the shear force of the pile satisfying the specific design safety factor can be determined.The example analysis shows that the pile shear force increases with the horizontal and vertical seismic influence coefficients,and the pile shear force is more sensitive to the horizontal seismic influence coefficient than the vertical one.The shear force of the pile satisfying the specific design safety factor decreases nonlinearly with the pile position approaching the slope top.
