| 摘 要： | 通过单拉伸试验，研究原状黄土的单轴拉裂特性。结果表明：密度和含水量是原状黄土抗拉强度的主要影响因素；原状黄土在接应力下的破坏一般为脆性破坏；抗拉强度与初始含水量呈幂函数关系，抗中度与凝聚力有良好的线性关系；试样破坏时的极限拉应随初始水量的增大而变大。

| Abstract: | Uniaxial tensile test is performed to study the uniaxial tension crack characteristics of undisturbed loess. Results indicate: Density and water content are primary influence factors affecting the tensile strength of undisturbed loess; Failure of undisturbed loess under tensile stress is generally brittle failure; Tensile strength and initial water content display a power functional relation; Tensile strength and cohesion have a good linear relation; The ultimate tensile strain of sample at failure grows according as the initial water content is increased. |

| Keywords: | Loess Tensile strength Water content Cohesion |
