摘要
在大量实验数据的基础上,详细分析了水 土体系中铁与水溶液发生的一系列物理化学反应,深入探讨了铁的含量、存在状态对土结构强度的影响机理.并指出,实验过程中土中的总铁含量和土体结构强度随着浸泡时间呈波浪状起伏,其原因是实验环境(水溶液中离子的种类和含量、水 土体系所处的氧化还原状态等)的改变.
Based on a large number of experimental data, a series of physicochemical reactions between iron and aqueous solution in the soilwater system is analysed in detail and the manner of influence of iron content and its existent form on the structural strength of soil is thoroughly discussed. It is also pointed out that the total amount of iron within the soil and the strength of soil structure vary with soaking time period in a manner of undulation during the process of experiment. This is caused by the change of experimental environment such as the kind and amount of irons in the aqueous solution as well as the condition of soilwater systemoxidative or reductive.
