Force Characteristics of Anti-Slide Pile of Bazimen Slope with Double Sliding Layer in Three Gorges Reservoir Area
摘要
Abstract
For complex slopes with double-layer sliding layers,the force characteristics of anti-slide piles are different from traditional single sliding plane.This paper takes the double layered sliding slope of Bazimen in the Three Gorges Reservoir Area as an example,the reinforcement mechanism of anti-slide piles in slopes with shallow and deep weak interlayers is investigated based on numerical and analytical methods.The factor of safety,slope displacement,and shear strain contour are obtained through numerical simulation.It is shown that the use of anti-slide piles for reinforcement can effectively improve the stability of the slope.The thrust behind the piles shows a significant discontinuous distribution.On this basis,the post pile thrust of the double-layer sliding slope is solved assuming a discontinuous trapezoidal distribution of post pile thrust combining with the transfer coefficient method.A theoretical calculation method for the displacement and internal force of the entire anti-slide pile of double-layer sliding slope is proposed based on the finite difference method.The comparison and verification between theoretical calculations and numerical simulation results have proven the reliability of the proposed theoretical calculation method,which can provide certain reference for the design of anti-slide piles of slopes with multiple sliding planes.关键词
