| 摘 要： | 利用点荷载作用于半无限空间的Mindlin位移解,根据位移协调条件得出内锚式锚杆受拉作用的解析解,然后推导出全长粘结锚杆、压力型锚杆的解析解,建立了这3类锚杆受拉作用解析解的统一表达式.利用所求得的解析解,研究了锚杆类型、土体弹性模量、锚杆孔径对锚杆应力分布的影响.结果表明:(1)3类锚杆的剪应力都是单峰值的曲线;(2)土体弹性模量增大,则锚杆剪应力峰值增大,但分布范围减小;(3)锚杆孔径增大,则锚杆剪应力峰值减小,但对其分布范围几乎没有影响.

| Abstract: | In order to obtain a general analytical solution of three types of anchors,an analytical solution of inner-bonded anchor under tensile load is obtained by assuming displacement consistency between anchor and soil,based on Mindlin solution of force at a point in the interior of a semi-infinite solid.Then the analytical solution is extended to the full-bonded anchor and compression anchor.Further,a general analytical solution of the three types of anchors under tensile load is obtained.The effect of anchor ty... |
