压实作用

In this paper,Laterite soil adjacent to some stake of the highway in Chenzhou, Hunan section from Xiamen to Chengdu was used to investigate the deformation characteristics and protection methods of the Laterite soil subgrade under the influence of environment factors.Properties like water-holding capacity,capillary rise, coupled heat-moisture transfer and wetting deformation of samples under different compactness were studied through a series of laboratory tests.In addition,by using meteorological data of two consecutive years in Chenzhou,coupled process of moisture transfer and subgrade deformation was stimulated under the impacts of groundwater and the atmosphere.Specific work done in this paper is as follows:(1) Samples under different compactness were subjected to a series of conventional laboratory tests,such as permeability,consolidation,contraction,shear test and etc.

The results showed that tillage had stronger compaction effect on Red soil. By analyzing retention properties, water content was higher in the same suction for Red soil. Field capacity and wilting coefficient were higher for Red soil than those for Lou soil, but effective moisture and saturated hydraulic conductivity were lower for Red soil. For Red soil, Lateral infiltration ability was stronger, infiltration rate was greater than one number degree for Lou soil and preferential flow occurred easily.

结果表明：耕作片红壤有较强的压实作用；从持水特征分析，同一吸力下红壤的含水量较高，田间持水量和凋萎系数也高于塿土，而有效水含量略低于塿土，饱和导水率却低于塿土1个数量级；从入渗特征分析，红壤的侧渗能力很强，入渗率比塿土高1个数量级，容易发生大孔隙流。
