Series Statement
AbstractThe Long Phu 1 Thermal Power Plant is located in Long Phu district, Soc Trang province, Vietnam. It occupies an area of about 115 ha and would play an important role in the implementation of the Electric Field Development Strategy of Vietnam Oil and Gas Industry up to 2025. The project has a total investment of 1,595.175 million USD and consists of two units with a total 1,200 MW capacity. In this study, the data were collected from geotechnical soil investigation works and reports conducted by PTSC Geo & Subsea Services Co., Ltd and were processed and analyzed for a detailed soil characterization under the Long Phu 1 Thermal Power Plant. First of all, a subsoil profile was constructed. It consists of the following soil layers from the surface downward, i.e, layer 1 is sand with silt, medium dense with water content (Wc) is from 12.3 % to 16.3 %; layer 2 is firm to stiff sandy lean clay with water content of an average of 32.4 %, liquid limit (LL) is around 47.4 %, plastic limit (PL) is around 20.4 %, void ratio (e) is from 0.7 to 1.2; layer 3 is soft to firm sandy fat clay with undrained shear strength ranges between 27.0 to 47.0 kPa, unit weight from 1.6 to 1.9 g/cm3; layer 4 is stiff sandy lean clay with SPT value ranges between 8 to 14 and water content with an average of 26.3 %; layer 5 is very stiff sandy lean clay with undrained shear strength from 64 to 118 kPa; and layer 6 is very stiff to hard lean clay with sand with SPT value ranges between 18 to 35, unit weigh from 1.7 to 2.0 g/cm3. There are some correlations between compression index, undrained shear strength and water content, void ratio, and unit weight were found as bellows: Layer 3 Su (UU) ~ Wc; Su = -1.134Wc + 90.15 (R2= 0.82) Su (UU) ~ γw ; Su = 7.48γw - 89.91 (R2=0.81) Su (UU) ~ e0 ; Su = -70.15e0 + 128.95 (R2=0.86) Layer 5 Su (UU) ~ Wc; Su = 3.7337Wc - 14.88 (R2=0.45) Su (UU) ~ γw ; Su = -35.4623γw + 758.916 (R2=0.38) Su (UU) ~ e0 ; Su = 166.034e0 - 42.4 (R2=0.49)
