The study results reveal some laws : ( 1 ) two failure modes exist in different obliquity slope and influence the internal force of soil nailing ; ( 2 ) the connection between face shield and soil nailing determines the distribution of the axial force along length ; ( 3 ) the influence of face shield involves its connection with soil nailing and its stiffness on soil nailing wall ; ( 4 ) the transversal effect of soil nailing depended on the joint of nail head is little ; ( 5 ) the maximum axial forces of other soil nailings except the first soil nailing increase gradually with excavation 研究表明: ( 1 )素土坡随着坡角的变化,存在两种破坏方式,破坏方式不同,土钉受力状态不同; ( 2 )土钉和面层的连接方式决定着土钉长度方向上的轴力分布形态; ( 3 )面层主要通过面层与土钉的连接和面层的本身刚度两个方面对土钉内力和墙体变形产生影响; ( 4 )土钉横向抗剪抗弯作用的发挥程度和土钉钉头的连接方式有关,但作用不大,实际设计时可以忽略其影响; ( 5 )随着坡体的开挖,第一排土钉的最大轴力变化不大,其它土钉的轴力都稳步增加。
