Understanding of the Recently Deposited Soil in Beijing Area
-
摘要: 新近沉积土自上世纪50年代被认识并引起工程界重视,目前在实际工作中的判别分析仍存在难点。为加强认识,通过比较总结前人的知识经验,并结合笔者在北京地区从事岩土工程勘察的实践,阐述了北京地区新近沉积土的基本特征与分布,着重探讨了其主要物理力学性质及地基承载力等工程特性,并对其定性、定量判别方法作了总结讨论。Abstract: The recently deposited soil was recognized in 1950s. But now in engineering practice there're still some difficulties in distinguishing recently deposited soil. In order to know this kind of soil better and instructing the work of geotechnical investigation more effectively, summarization of other researchers' knowledge and experiences was combined with the author's practical analysis. Based on these, the basic characteristics and distribution of recently deposited soil in Beijing area were expounded firstly. Then the engineering geological characteristics such as physical and mechanical properties and foundation carrying capacity were discussed. Finally, the discriminances about recently deposited soil were concluded.
