为了研究黄土的抗剪强度指标与含水率和压实系数的关系，对不同含水率和不同压实系数下的重塑黄土进行了室内三轴剪切试验。试验结果表明：各种压实程度不同的重塑黄土黏聚力均随含水率呈抛物线形变化，可用二次多项式表示；内摩擦角随含水率增大呈线性减小；不论含水率的大小，重塑黄土黏聚力均随着压实系数的增大而增大，可用二次多项式表示。分析了重塑黄土力学特性影响因素，可为青海地区黄土工程的设计、施工提供指导。

To study the relation among shear strength,moisture content and compacting coefficient ,the paper conducted indoor triaxial shear experiments to loess of different moisture contents under various compacting coefficients.The results indicate that as the moisture cotent goes up ,the cohesive force of all the loess samples changes in a parabola-curve pattern,which can be concluded in a quadratic function;while,the internal friction angles decrease.However,the cohesive force rises with the increase of the compacting coefficient irrespective of the level of its moisture content , whose relations can also be concluded with a quadratic function.The paper also analyzes the possible parameters that may influence the mechanical performance of the remolded loess , which is of reference value to the design and construction of the loess project in Qinghai province .
