中文摘要: |
视锚杆和周围介质为弹性材料,在弹性半空间里,利用Mindlin位移解,根据拉力型锚杆实际工作状态,推导出拉力型锚杆锚固段轴向应力和弹性粘结应力分布的方程.并分析相关岩土参数对锚固段轴向应力和剪应力的分布的影响,得出影响较大的几个因素,为拉力杆的力学分析和工程设计提供理论依据。 |

This research provides a theoretical basis for the pull rod mechanics analysis and engineering design.In accordance with the above,we can analyse related geotechnical parameters on the axial stress and shear stress distribution of the anchorage segment,and influence of several factors can be concluded.According to tensile type anchor rod under the actual working condition,we can deduce the equation about the distribution of axial stress and elastic bond stress of tensile type anchors anchoring section when the anchor bolt and the surrounding medium are elastic materials by Mindlins displacement solution in elastic half-space. |
