| 摘 要： | 基于空间一点受力的位移解形式--Mindlin 位移解, 结合已有文献对节理面位置处全长粘结锚杆受力的假想形式, 将边坡下滑力简化为作用在锚杆上的集中力, 推导出锚杆沿杆长方向的轴力、剪应力的表达形式. 将推导结果在岩质边坡中进行应用, 得出不同岩体类型岩质边坡锚杆沿杆长方向受力的轴力、剪应力图示.

| Abstract: | Based on the Mindlin’s solution of displacement for a concentrated force in space,combined with the well assumed mechanical characteristic form of the wholly grouted anchor in a joint plane,with the sliding force as a concentrated force,the formulas for the axial force and the shearing stress along the anchor are obtained.With them applied to rock slopes,the axial force and the shearing stress along the bolt for rock slopes of rock mass of different types are obtained. |
