| Abstract: | The basic features and acoustic-physical properties of calcareous seatloor soils in the tropic sea area are obviously different from those of sediments mainly composed of terrigenous materials in the South China Sea. Generally, calcareous soils, composed of carbonate particles of marine organism remains, have the characteristics of high water content, high porosity, low wet density, high sound velocity and greatly varied compressive strength. Recognizing the differences between calcareous soils and terrigenous sediments and engineering geologic significance of calcareous soils is crucial for sea floor geologic research and geolechnical stirvey for pile jacket platform foundation design. |
