| Abstract | The research project is located at Than Thuan Ward, Dam Doi District, Cam Mau Province, with a shallow water depth varying from 2.50m to 3.50m in Vietnam. This study mainly focuses on constructing the geotechnical characterization of a subsea soil profile based on in-situ testing and laboratory testing data collected for a near-shore wind farm site in Vietnam. The data were collected from the piezocone penetration test (CPTu), field vane shear test, and laboratory testing report conducted by Technical World Group Company. To analyze and interpret the raw soil to examine the behaviour of soils, applied Cone Penetration Test (CPTu) Processing Software NovoCPT, which NOVO Tech Software supports. A soil profile was constructed based on CPTu and laboratory data analysis. They are the Sand and silt mixture layer(0-4m), Fat Clay layer(4-32m) generally, lean clay layer (32-44m for boreholes 1,2 and 3), (32-34m for borehole6) while Clayey sand layer(30-40m around for borehole 4 and 5), for borehole 1 and 2 clayey sand layer (38-45m around), second Fat clay layer (26-34m around for borehole 4,5 and 6), Silty Clayey Sand layer ( 44-50m for borehole 4,5 and 6) and second lean clay layer (50-62.95m borehole 4,5 and 6) appropriately. Also, the soil profile was presented and compared with CPTu and field vane shear in-situ undrained shear strength and direct shear, consolidated undrained, unconsolidated undrained, and unconfined compression laboratory tests are presented to extract reliably applied parameters for different geotechnical preliminary design works. |
