摘　　要：通过室内试验 ,研究和探讨了重塑黄土处于最佳含水量下及非最佳含水量下 ,击实功与龄期对其力学特性相关参数的影响。试验表明 ,在最佳含水量下 ,抗剪强度指标在本试验击实功范围内随击实功的增加呈线性增长 ;得到了以相同含水量、不同击实功制备的重塑黄土 ,击实功、龄期与抗剪强度指标三者之间的相互关系的一些结论 。Based on laboratory test,the influences of compactive effort and age to the parameters correlated to the mechanical properties of remolding loess under the condition of optimum and non-optimum moisture content,the shear strength indexes increase linearly with compactive effort at the range of the test.Some conclusions were given about the correlaltionship among compactive effort,age and shear strength indexes,and the internal reasons for the conclusions were analysed primarily.
