中文摘要：

不稳定边坡在开挖、降雨影响下会产生较大的土体侧向位移，导致邻近抗滑桩产生附加位移及弯矩．为此，文中基于Winkler地基梁模型，采用简化的桩周土体弹塑性本构关系来模拟非线性桩-土的相互作用，提出了抗滑桩与土坡相互作用的弹塑性地基反力法控制方程组，依据桩身响应在滑面处连续条件及桩顶底边界条件求得桩身响应的解析解矩阵表达式．最后，将文中的解析解与已有模型试验实测值进行对比分析，结果验证了文中解析方法的可靠性．

英文摘要：

Large lateral soil movement usually occurs in many unstable slopes due to the excavation or rainfall, which results easily in additional displacement and bending moment in adjacent stabilizing piles. In order to solve this problem, based on the Winkler foundation beam model, the simplified elasto-plastic constitutive relation of the pilelateral soil is adopted to simulate the nonlinear pile-soil interaction, and a set of four-orders differential governing equations based on the elasto-plastic subgrad slope interaction. Then, the matrix expression to its continuity conditions on the sliding face e reaction method are devised to describe the stabilizing pile-soil of the analytical solutions of the pile response is deduced according and boundary conditions at the top and bottom of the pile. Finally, the analytical solutions obtained through the proposed method and the existing measured values in model tests are compared, thus verifying the reliability of the proposed analytical method.
