大连地区红粘土特征研究
摘要:大连地区存在发育的红粘土。该土与石灰岩及粘土在化学成分上进行了对比,分析了某些元素流失与聚集的原因,并对其特有的物理特征进行了原始状态、风干状态的水浸试验与土体的收缩试验。从而对该地区红粘土风干后,遇水崩解不可恢复的特殊性,以及土体卸荷在保持原有天然含水量的情况下,呈现稳定状态的合理解释。
Abstract:The developed red clay exists in Dalian district. Through being compared with limestone and clay in chemical composition, the reasons why some elements of the red clay run off or collect are analyzed. In order to reveal its peculiar physical characteristics, the water invade test and the soil body shrink test on the red clay are respectively carried out in aboriginal and air-dried state. Through the test resuts, some phenomena of the red clay are explained, such as the irrecoverability of this red clay disintegrated by water, and the stability of earth body excaved at natural moisture condition.
