| 摘 要： | 提出利用杆系有限元，考虑地梁与岩土体相互作用的方法，对边坡加固中的预应力锚索框架地梁进行计算。基于线弹性Winkler地基模型，分别考虑结构的弯曲变形和扭转变形，对框架地梁有限元计算模型进行了详细地分析说明。应用该方法对某工程实例进行了计算，与实测值的对比分析结果表明了该方法的可行性。

| Abstract: | A method, using pole system FEM and considering the interaction between the foundation beam and the rock and soils, is proposed to calculate the frame foundation beam with prestressed anchor-cable used in reinforced slopes. Based on the linear elastic Winkler model, the FEM model of the frame foundation beam is analyzed in detail by taking the structural bending and torsion deformation into account respectively. An engineering case is calculated using the method; and the comparison between the computing data and the testing data in situ proves the method is feasible. |
