Understanding of the Recently Deposited Soil in Beijing Area

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.
