摘　　要：采用正交设计方法,以碱激发超细矿粉改性生土材料的抗压强度为指标,分析了生土颗粒粒径、生土与超细矿粉比例、复合碱性激发剂掺量等因素对碱激发超细矿粉改性生土材料抗压强度的影响,结果表明:各因素影响改性生土抗压强度的顺序为复合碱性激发剂掺量、生土颗粒粒径、生土与超细矿粉比例;复合碱性激发剂掺量的影响最大,最佳的复合碱性激发剂掺量为6%。By means of orthogonal design method, with the compressive strength of improvement for raw-soil material base on alkali-activated su-perfine slag as the index, the paper analyzes the effect of compressive strength for raw-soil material base on alkali-activated superfine slag, along with the particle size of raw-soil, superfine slag and raw-soil ratio and the content of alkali-activated. The test results show： the importance order of the three influencing factors on the compressive strength for raw-soil material base on alkali-activated superfine slag is the content of alkali-ac-tivated, the particle size of raw-soil and superfine slag and raw-soil ratio, and the optimal content of alkali-activated is 6%.
