摘要

运用非线性有限元方法，对一种新型的预应力锚杆柔性支护技术进行了数值分析。基于反映预应力锚杆柔性支护机理模型，对其力学性能进行了研究，并与两种不同间距的土钉支护进行了类比。结果表明：对变形要求严格时使用该种预应力锚杆柔性支护可以更有效地控制变形。

Abstract

A new kind of excavation support technology

pretressed anchor flexible retaining method

is numerically analyzed using nonlinear finite element. The model for prestressed anchor flexible retaining is established to study its mechanical performance. Also

the comparison of two other kinds of different spacings soil nailing is proceeded. The result indicates that the prestressed anchor flexible retaining method can control deformation more effectively for the strict deformation requisition.
