sandy loam

Extensive field and laboratory tests were performed on the natural deposits of sandy loams to demonstrate the very difference in the behavior from clayey soils in the grain size distributions,strength characteristics and plasticity chart,etc.

大量室内外试验研究清楚表明亚砂土在粒度分布、强度特性、压缩性和塑性图等方面与一般粘性土完全不同,因此室内固结试验所得到的天然沉积亚砂土的固结系数与一般粘性土固结系数基本相同是明显不合理的。

According to practical projects,universal contradiction phenomenon exists in consistency partition and mechanics character of sandy loam,which is one of slow liquid limit clay.

鉴于实际工程中,低液相粘性土之一的亚砂土的稠度划分与其力学特征之间普遍存在矛盾的现象,采用灰理论中的关联度分析,对粘性土物理状态指标与力学特征指标之间的相关性进行分析是比较合理贴切的,且对今后的研究与工程应用有重要的参考价值。
