摘要

饱和软黄土是黄土地区一种特殊性岩土。结合西安城区和北环铁路工程勘察的结果,分析了西安地区饱和软黄土的分布规律及其物理力学性质,讨论了饱和软黄土分布上的差异,从地质环境角度探讨了北环铁路饱和软黄土分布的成因,提出了上层滞水含水层也存在饱和软黄土的观点。
Saturated soft loess is a special soil in the loess area,Xi′an,China.This paper presents the surveying results ofthe saturated soft loess at the urban area and the northern railway area in Xi′an.The paper further presents and analyzes the spatial distribution and the physical properties of saturated soft loess.The differences between the spatial distributions of the two areas are discussed.The causes of forming the saturated soft loess in the two areas are examined.A hypothesis that there is saturated soft loess in the upper perched water zone is suggested.
