| 摘 要： | 依托ABAQUS大型有限元程序,以坡体塑性区贯通和关键点位移突变为失稳判据,实现边坡强度折减法的参数化训练模型,计算了一个边坡算例,通过与Bishop极限平衡法计算结果的对比,验证了参数化训练模型的有效性和准确性,最后将研究成果应用于谷竹高速公路某段边坡,对坡体的安全性进行了分析,并提出了相关建议。

| Abstract: | Based on ABAQUS large-scale finite element program,taking slope plasticity interpenetration and critical point displacement sudden change as the instability basis,the paper realizes the parametric training model of slope strength reduction method,calculates the side slope algorithm,compares it with the Bishop limit balance calculation method,and testifies the effectiveness and accuracy of parametric training model.In the end,it applies the research result into one side slope section of Gu-Zhu highway,and analyzes the security of the slope,and puts forward corresponding suggestions. |
