二灰稳定砂砾抗剪强度影响因素的灰色关联度分析

针对二灰稳定砂砾抗剪强度的影响因素,采用灰色关联度分析方法,分析了粗骨料间隙率、结合料含量、细集料含量、粗集料含量、最大干密度和最佳含水量等因素对二灰稳定砂砾抗剪强度的影响程度,为二灰稳定砂砾的优化设计提供理论依据。

Due to the influencing factors of evaluation index for shear strength of lime fly ash stabilized gavels ,the paper analyzes the influence degree of coarse aggregate clearance percentage,binder content, fine aggregate content,coarse aggregate content , maximum dry density and optimum water content on shear strength of lime fly ash stabilized gravels by use grey correlation analysis,in order to provide theoretical basis for the optimum design of lime fly ash stabilized gravels.
