摘要: 我国南方有许多含有大量游离氧化铁的红色粘土(砖红壤),它们是在湿、热成土条件下形成的,具有由成份和结构引起的特殊工程性质。它们往往含水量高,孔隙比大,但力学强度仍然较高,即存在所谓物理指标和力学参数似乎相互矛盾的现象。本文着重讨论游离氧化铁对砖红壤的工程性质(如强度、膨胀特性等)的影响。研究结果表明,土中的游离氧化铁的形成、淋失和结晶程度的不同,土的工程性质也各异;土的物理力学性质会随周围环境的物理化学因素变化而变化。
Abstract: In southern China, there are a great amount of red clay(laterite) which contains some free ferric oxide. Owing to its composition and microstructure developed under hot, wet soil-forming conditions, the clay has several special characteristics. Although the water content and void ratio of laterite are greater than similar clay soils, its strength is still higher than the others. There seems to be a contradiction between its physical parameters and mechanical properties. In this paper, the effect of free ferric oxide in laterite on its engineering properties, such as strength, swelling properties and others is discussed. The research result shows that special properties of laterite are the result of various conditions of formation, loss and crystallization degree of free ferric oxide, and its physical and mechanical properties will change with variation of physicochemical circumstance.
