土的超固结性地质成因分析

以经历红土化作用的红土、东部沿海平原区的浅层硬土层及地表硬壳层等超固结土为例,论述了它们形成的地质历史;形成过程中的成土作用及垂向变化特征。结论是堆积后风化淋滤作用是造成上述超固结性土的主因,其次是上覆土层的自重压密。

Geologic Reason Analyses on Super Consolidation of Soil

This article give some examples, as the red soil of laterization, coastal plain of shallow hard layer and hard crust layer, discuss the geologic history which it come out and the course of pedogenesis and characteristics of perpendicular changes. Results that the leaching process is the major reason of the soil owns super consolidation during the course of pedogenesis after deposition, the minor reason is the pressure of its own weight on the surface of soil layer.
