STUDY ON THE STRUCTURAL STRENGTH OF UNSATURATED SOILS

摘要: 本文提出非饱和土结构强度的概念,从膨胀土的结构模型导出结构强度公式τ_s=cu_s^α,分析了结构强度公式成立的条件,并把结构强度公式推广到符合公式条件的所有类型非饱和土。

Abstract: The concept of structural strength is presented in this paper. Based on the structuralmodel of expansive soils, a formula on structural strength is obtained as τ_s=cu_s^αtgø¹.The suitable conditions of the structural strength formula are discussed. The formula is also extended to other unsaturated soils.
