摘要
主要介绍合肥市二环路用生石灰,石膏改良膨胀土的室内试验研究,并根据试验资料说明生石灰、石膏改良膨胀土的效果。同时提出一种用生石灰—石膏改良合肥膨胀土的最佳配方。大量的试验结果表明,用该配方改良后的膨胀土其单轴抗压强度,水中稳定性、耐久性都有显著提高。经十几年来在合肥市二环路上应用效果良好。
This paper mainly introduced the indoor experimental study on improving the expansive soil with quick lime and gypsum for the Hefei second-ring roads, including the test resnlts -simultaneously gave the best formula of improving the soil with quick lime and gypsum. Massive testing results indicated that the soil improved with this formula showed remarkable enhancement in its single axle compressive strength, stability in water and durability. The result is encouraging after a dozen years of application in the Hefei second-ring roads.
