摘　　要：通过运用正交试验和XRD等方法，研究了改性石灰粘土固化剂的最佳配比及各种外加剂的增强机理，试验表明：对于最佳含水量的土壤，改性石灰粘土固化剂的最佳配比为：生石灰84％，石膏3％，硫酸钠5％，硫酸铝8％。用它固化的土壤州抗压强度比同一条件下用生石灰固化的土壤提高56．9％。外加剂的作用机理在于使稳定土早期形成较多的钙矾石。In this paper the soil stabilizer manufactured from modified lime is studied by means ofthe mathematics method and XRD analysis. The results show that the soil stabilizer with 84%(wt.) quicklime,3% gypsum,5% sodium sulphate and 8% aluminum sulphate is the best one forthe soil with the optimum water content. The 7-day compressive strength of soil stabilized with themodified lime stabilizer is 56. 9% higher than that with only quicklime- The effect of the admixtureis to produce more Aft(3CaO. Al2O3 3CaSO4. 32H2O) in the soil stabilized in the early period.
