The Pile Reinforcement Effect to the Displacement of Geotechnical Materials in the Stratified Rock Slope

Abstract

Piles have been used in geotechnical engineering to stabilize slope for many years and the methodology has been accompanied by a significant bibliography. In the past, methods of analysis of pile-reinforced slopes have often used limit equilibrium methods, where rock–pile interaction was not properly considered. Recently, with rapid development of computer techniques, numerical methods using either finite element or finite difference methods have been widely applied in slope engineering, and have been shown to offer many advantages over limit equilibrium method, such as the ability to develop the critical failure surface automatically with fewer assumptions. However, seldom studies have been done on the stratified rock slope reinforced by piles, so in the present paper, the numerical simulation software FLAC3D is adopted to model the stratified rock slope, then the reinforced effect like deformation and stress of slope are studied, to give guidance for the real practice.
