The soil microstructure theory and technical method are used to stady the microstructure features of cohesive soil in the southern Yellow Sea oil and gas resource area,and in combination with the physico-mechanical property parameters of undisturbed soil samples the relations of grain contact,accumulation and porosity to soil physicomechanical properties are studied.

Based on the study of geologic hazards and geologic hazard environments in the East China Sea oil and gas resource area, the weighted statistical model and geographic information system method are used to quantitatively evaluate the sea bed stability in the study area.
