Limit Analysis of Slope Stability During Pile Driving Considering Energy Dissipation Due to Deformation of Inner Friction
In most existing limit analysis studies of slope stability, it was often assumed that the logarithmic spiral landslide body is a rigid body, and the energy dissipation in the process of landslide occurs only on the sliding surface. Although the calculation of energy dissipation could be significantly simplified by employing this assumption, the energy dissipation due to internal friction could not be taken into account in the slope stability analysis, thereby often leading to inaccuracy in the evaluation of slope safety factor. In this paper, a multi-block partitioning method is adopted to quantify the internal dissipation during the pile driving process. By employing the limit analysis method, the safety factor incorporating the effects of energy dissipation due to internal friction for evaluating the slope stability subjected to pile driving is calculated. Comparison studies of the results with and without consideration of internal-friction-induced energy dissipation are presented and discussed. The results show that the slope safety factor with consideration of the energy dissipation due to inner friction-induced deformation is greater than its counterpart neglecting such effects. The energy dissipation significantly contributes to improving the anti-slide capacity of slope, which should be taken into account in the slope stability analysis in practice.
