| 摘 要： | 红土是在亚热带、热带湿热气候条件下风化形成的一类区域性残积土。天然状态下的红土具有含水量、液限、塑限值较高，孔隙比大，容重低等一些物理性质。同时红土又表现出较高的力学强度及较低的压缩性。这一异常现象的出现与红土中富积的游离氧化物，尤其是游离氧化铁有着密切的关系。本文着重由三个方面就红土中游离氧化铁的作用及其机理进行了初步研究。

| Abstract: | Laterine is a weathering and leaching residual soil under sub-tropical and tropical climate. It is one kind of special and regional soil.Laterite has properties with higher natural moisture content,highet planicity and Pore ratio, but in the engineering geological properties laterite showed higher strength and mid-compressibility. As general thinking,this abnomal phenomena emergeing is oweing to free ferric oxide which accumulated richly in laterite.In this Paper,from three aspects author have discussed action of free ferric oxide in laterite,besides have probed into action mechanisim of free ferric oxide. |
