摘要

考虑土体的非均质性与各向异性，结合预应力锚索锚固段土体的破裂形式，利用非线性强度准则，根据极限状态下力的平衡原理，推导出一个可考虑土体非均质性、各向异性与非线性破坏性质等多种因素影响的锚索极限抗拔力计算公式，并通过理论计算，分析土体非均质性、各向异性以及非线性强度系数对锚索极限抗拔力的影响。计算研究表明，土体的非均质性与各向异性对锚索抗拔力的影响显著，随着土体非均质常数的增加，锚索极限抗拔力不断提高，而随着各向异性系数与非线性强度系数的增加，抗拔力则有所下降；当土体非均质常数与各向异性系数提高时，土体破裂范围不断增大，研究结果可为锚索锚固体的设计提供一定参考。

Abstract

Considering the non-homogeneity and anisotropy of soil mass

according to the shape of rapture surface of anchor cable and nonlinear failure criterion

a formula of ultimate pullout force of anchor cable

considering the non-homogeneity

anisotropy

nonlinear failure characteristics and many other factors

is deduced based on limit equilibrium principle. Theoretical calculations are conducted to analyze the influences of non-homogeneity parameters

anisotropy parameters and nonlinear parameters on ultimate pullout forces of anchor cables. The results reveal that

with the increase of non-homogeneity parameters

the ultimate bearing capacity of anchor cable increases; but with the increase of anisotropy parameters and nonlinear parameters

the bearing capacity of anchor cable decreases; the rupture width expands with the increase of non-homogeneity parameters and anisotropy parameters

which provides a certain reference for the design of anchorage body.
