Abstract

. In order to determine the relationships between the soil stiffness constants of cohesive modulus of deformation, friction modulus of deformation and soil constant value and the rolling resistance, a series of tests was conducted using two types of loam and clay loam soil textures at four moisture contents of 10, 20, 30 and 40% and five loading speeds of 1, 2, 3, 4 and 5 mm s –1 . The results showed that all of the independent fac - tors had a significant effect on the soil stiffness constants, so with increases in moisture content and loading speed, the soil stiffness constants of cohesive modulus of deformation, friction modulus of deformation and soil constant value varied significantly. The highest cohesive modulus of deformation and friction modulus of deformation values were obtained at a moisture content of 10% and loading speed of 5 mm s –1 in a clay loam soil. All param - eters were significant in calculating the rolling resistance using Bekkers’ relationship. With increases in soil moisture content, the rolling resistance increased, while increasing the loading speed reduced the rolling resistance significantly. In general, the highest rolling resistance value of 16 887.1 N was obtained at a moisture content value of 40% and a loading speed of 1 mm s –1 in loam soil.

评估贝克尔参数的变化及其在确定滚动阻力中的应用

.为了确定土壤的内聚变形模量、摩擦变形模量和土壤恒定值等刚度常数与滚动阻力之间的关系，在 10%、20%、30% 和 40%四种含水量和 1、2、3、4 和 5 mm s -1 五种加载速度下，使用两种壤土和粘壤土质地进行了一系列试验。结果表明，所有独立因素都对土壤刚度常数有显著影响，因此随着含水量和加载速度的增加，土壤刚度常数（内聚变形模量、摩擦变形模量和土壤常数值）也有显著变化。在含水量为 10%、加载速度为 5 mm s -1 的粘壤土中，内聚变形模量和摩擦变形模量的值最高。所有参数在使用 Bekkers 关系计算滚动阻力时都很重要。随着土壤含水量的增加，滚动阻力也随之增加，而加载速度的增加则显著降低了滚动阻力。一般来说，在含水量为 40% 和加载速度为 1 mm s -1 的壤土中，滚动阻力的最高值为 16 887.1 N。
