外文摘要：A soil-pile interaction model of pile stabilized slopes is developed by using the FLAC3D program to evaluate the effect on the distribution of lateral soil pressure caused by varying shear strength parameters of sliding mass. On the basis of determining the distribution of load acting on pile side, special attention is given to the horizontal stress and residual driving force using three-dimensional finite difference analysis. The experimental data confirmed that the distribution of soil horizontal stress is reasonable to be described by parabola profile. The horizontal stress increases with depth, while the growth rate is declining. The gap between the horizontal stress acting on the pile top and the stress acting just above the sliding zone is diminished by increasing the friction angle and cohesion of sliding mass. The relationship between horizontal stress of sliding mass near pile-top and friction angle, cohesion approximately meet parabolic and exponential distribution respectively. Through comparative studies, it has been found that the residual driving force is reduced by increasing friction angle and cohesion. The position parameter k for describing application position of residual driving force decreases with increasing shear strength parameters which can be expressed by exponential function. ? 2014 ejge.
