| 摘 要： | 假定锚侧摩阻力与剪切变形呈非线性变化,考虑锚侧土体在影响区域内符合非线性弹性理论,运用剪切位移传递法,建立了抗浮锚杆计算模型,推导了锚侧剪应力与剪切位移的关系式。通过模型描述受荷状态下抗浮锚杆的轴力、摩阻力、位移的变化形态,分析了锚杆应力变化的工作机理,并预估了其极限承载力。

| Abstract: | Based on the assumption that the frictional resistance and shear displacement was nonlinear variation, and the soil had nonlinear elastic behavior, the equation of shear stress and shear displacement was made out by shear displacement transfer method. The model described the changes of axial force, frictional resistance and displacement under the various loadings, and analyzed on the working mechanism of anchor shear stress change. At the same time it estimated the bearing capacity limit. |
