摘要:

石灰改良是对高液限土的一种较好的处治方法。针对浏醴高速公路路床高液限土,在掺加生石灰改良后开展了一系列试验工作,研究不同剂量的石灰处治高液限土的强度变化规律与物理力学性质。试验结果显示,在用4%~6%的生石灰改良后,高液限土做为路床用土其路用性能良好,可满足高速公路路基填料要求。

Abstract:

Several laboratory experiments were completed by adding different ratios of lime to modify the high liquid limit soil of LiuLi Expressway,and the physico-mechanical properties and the strength change laws of the lime improved high liquid limit soil were studied.Through synthetically considering testing result and economic benefit,the best lime quantity of the high liquid limit soil of Liu-Li Expressway.The results show that the high liquid limit soil can be well used as subgrade filling of expressway after being treated with 4% lime.
