Studing on the changing rule of lime modification expansive soil, such as free swelling ratio, swelling strength, non-side limitation compressive strength.
研究了膨胀土加入石灰改性后，其无荷膨胀率、膨胀力、无侧限抗压强度等指标的变化规律。
The test results indicate that: 1) Compared with unmodified soils, the free swelling ratio, plastic index and clay fraction of fly ash-treated soils and Lime-treated soils decrease obviously.
试验结果表明：1）相比于未改性土，粉煤灰改性土和石灰改性土自由膨胀率、塑性指数、胶粒含量都显著降低；
