摘要 运用非线性有限元分析方法,研究了方形锚板埋深、系缆力角度等因素对极限承载力的影响,并绘制出了塑性屈服包络线.根据塑性理论,塑性屈服包络线可用于预测极限承载力及锚板的拖曳轨迹. The nonlinear finite element method has been used to investigate the effect of square anchor embedment depth and inclination.The results were presented in the form of plastic yield locus.According to the theory of plasticity,the plastic yield loci can be used to predict the ultimate holding capacity and the dragging trajectory.
