摘　　要：在岩土问题分析中 ,一直采用莫尔 -库伦强度理论 ,该理论适用于单一材料 ,且不考虑中间主应力σ2 的影响 .本文运用统一强度理论求解纤维加筋土地基的承载力 ,推导出承载力表达式 ,同时结合实例检验 。Mohr Coulomb strength theory, used to analyze soil and rock engineering for many years, can only solve the problems with one kind of material, and neglect the effect of σ 2 stress. Unified strength theory is applied and bearing capacity of reinforced soil composed of different kind of materials is obtained. The method in this paper is proved credible through the engineering calcuation analysis.

关 键 词：纤维加筋土 统一强度理论 临界荷载
