摘要
考虑土钉的弯剪作用、土的分层性以及微型桩的抗剪作用,探讨了超前微型桩+土钉复合型支护的稳定性分析方法,建立了其内部稳定性安全系数的计算公式,并分析了土钉弯剪作用对支护稳定性的影响。
Considering the bending and shearing capability of soil nailing, the stratification of soil and the shearing capability of micro-pile, the stability of composite support of micro-pile ＆ soil nailing is discussed, the formula of safety coefficient of inter- nal stability of it is established and the stability of composite support is analyzed, which is influenced by the shearing capability of soil nailing.
