摘　　要：在地震作用下桩锚之间相互作用,其受力关系复杂。运用FLAC3D有限差分软件建立数值模型,并施加简化后的汶川地震波,分析地震作用下桩锚支护边坡的位移、加速度、锚杆轴力响应等动力特性。结果表明:桩锚结构对边坡土体位移和边坡的稳定性具有良好的控制作用。Under the action of earthquake,the stress relationship due to pile-anchor interaction is so complicated.With FLAC3D finite difference software,the numerical model was established and then applied by simplified Wenchuan seismic wave to analyze the dynamic characteristics of pile-anchor structure under seismic effect,such as the displacement and acceleration response of slope,and the axial force response of anchor bolt.The results show that the pile-anchor structure plays a good role of controlling the displacement of slope soil and the stability of slope.
