为能全面考虑结构性黄土的抗拉抗剪特性.通过抗拉强度、单轴抗压强度和常规三轴剪切强度等三种试验,针对结构性黄土的应力路径和强度破坏线进行分析.基于全面而合理地描述结构性黄土强度的抗拉强度特性和抗剪强度特性的观点,建立一种能综合考虑抗拉特性和抗剪特性的结构性黄土双曲线强度理论公式,并通过一系列数学推导证明了双曲线强度公式的理论正确性.研究表明:新建立的结构性黄土双曲线强度理论公式能较为有效、合理地反应结构性黄土的抗拉、抗剪特性.
In order to fully consider the tensile and shear resistance characteristics of structural loess, the stress paths and strength failure lines of structural loess were analyzed by three tests including tensile strength, uniaxial compressive strength and conventional triaxial shear strength. Based on a comprehensive and reasonable view of the tensile strength and shear strength characteristics of structural loess, a theoretical formula for the strength of structural loess with respect to both tensile and shear properties was established and passed through a series of The mathematical derivation proves the theoretical correctness of the hyperbolic strength formula. The research shows that the newly established theoretical formula of structural hyperbola strength can effectively and reasonably reflect the tensile and shear resistance characteristics of structural loess.
