摘要
通过对几种代表土样在经过不同化学掺和剂的改良后的物理、化学性质的变化对比分析,揭示原土经过改良后填料在最大干密度、最优含水量、液塑性、颗粒组成、渗透性、水稳性、收缩性以及矿物成分等方面的物理、化学性质变化情况。
Based on the comparison of several kinds of typical soils, this paper analyses the variety of physical and chemical property of the soils through soil melioration by chemical adulterating agent, and introduces the characteristics of the meliorated soils in physical and chemical aspects such as maximum dry density, optimum moisture content, penetrability, and water stability.
