Abstract

Abstract

A micro-structural theory and a technical method of Quaternary geology are used to study engineering geological estimating problems of sediments in off-sea of the Zhujiang River mouth.Soft soil structures,microstructure and classification characteristics are analysed by using method of electron microscope.On the basis of analysing physical-mechanical characteristic parameters,the relation among grain contact,grain accumultion and porosity with physical-mechanical characteristics of sediments are studied.The study result shows that there are 6 micro-structural types in sediments of off-sea of the Zhujiang River mouth,and among these,the mixed contact structural sediment has higher compressive strength than others.
