A STUDY ON THE RELATIONSHIP BETWEEN GEOTECHNICAL PROPERTIES AND CLAY MINERAL COMPOSITION OF HANOI SOFT SOILS IN SALINE MEDIA

Abstract:
Soft soil in Hanoi, Vietnam, is mainly originated from lacustrine, marsh, river and shallow sea sediment. This is the youngest formation with around 3000 years of age. To serve the research purpose, clayey soil samples at ten areas in Hanoi and some other places in the Red River delta were prepared. Mineral composition of soils determined by X-ray diffraction analysis showed that clay minerals are predominated by Illite, Kaolinite, Chlorite, and Montmorillonite respectively. Many previous researches indicated that in saline-saturated condition, types of cation in saline water and types of clay mineral and its predomination in soil layer as well decide the changing process of geotechnical properties in other manner. In this paper the initial relationship between geotechnical properties and clay mineral composition of Hanoi soft soils in saline-saturated media is established.
