粗粒土最大干密度理论计算方法研究

Research on the theory calculation method of maximum dry density of the coarse grained soil

通过引入细粒料最大干密度的校正系数及粗粒土的密度干涉系数和最佳含水量系数,在室内大型击实试验的基础上建立密度干涉系数及最佳含水量系数与粗颗粒含量之间的双对数关系,从而得出了粗粒土最大干密度和最佳含水量的理论计算公式。

Based on the introduction of the correction factor of maximum dry density of the coarse grained soil, density interference factor of the coarse grained soil, and its optimum water content coefficient, the density interference coefficient and the double logarithmic relationship between optimum water content coefficient and the content of the coarse particle is established based on the indoor large scale compaction test, thus getting the theory calculation formula of the maximum dry density and optimum water content of the coarse grained soil.
