| 摘 要： | 本文通过模拟环境中的有机质使游离氧化铁形态转化对典型红粘土工程性质的影响试验,系统地测试了游离氧化铁的形态分布与物性指标的关系。试验结果表明,在渍水条件下,游离氧化铁的形态转化对红粘土性质的影响不显著,但在渗水条件下,由于游离氧化铁的流失使得胶结作用减弱,它对红粘土工程性质的影响逐渐明显,其潜在的危害仍然是不容忽视的。

| Abstract: | In this paper,by simulating the form conversion of free iron oxide caused by the organic matter in environment,the relationship between free oxide status distribution and physical index is systemically measured and discussed.The result shows that the effect of the conversion on the engineering of the typical red clay is not so significant under the impermeable condition,whereas under the permeable condition,the effect gradually becomes significant with the draining of the free iron oxide caused by weakening cementation,so its potential damage is not neglected. |
