| Abstract | This study refers to the section Trung Luong - My Thuan as a part of the North – South highway, whose length is 54km and it passes through Tien Giang Province. Analysis of the site investigation data along the Trung Luong – My Thuan highway that passes through different geological conditions, to provide soil characterization and geotechnical parameters for highway design works. This re search, collection of the laboratory and In- situ testing data along the highway route, Performing soil characterization (layering and zoning) of the subsoil profile along the highway and Finding out correlations between some geotechnical parameters for each layer and zone. In the result, the subsoil profile along the Highway was divided into two zone, Zone I and Zone II. The subsoil profile to a depth of 76m is divided in to 7 main layers, as below: Weathered crust layer on the top, thickness about 0.4m to 2.6m; Layer 1 consists of two sub layer 1a Soft to very soft clay and 1b Soft clay with thin lenses of sand, from ground surface to depth of 2.7m to 42.0m: Layer 2, Underlying the surface layer to depth of 61.8m, This layer consists of two sub layer 2a Medium stiff to stiff clay and 2b stiff to very stiff clay; Layer 3, to depth of 30.5m is Medium dense clayey sand within thickness of 3.6m to 14.5m; Layer 4, to depth of 55.5m is very stiff to hard clay. Layer 5, to depth of 68.0m is dense to very dense sand. Layer 6, underlying the dense to very dense sand layer to depth of 55m to 62m is very stiff to hard silty clay; Layer 7, Underneath is residual dense to very dense clayey sand. The average of physical and mechanical properties of soil and the consolidation properties an d the relationship between consolidation index versus water content, void ratio and Liquid limit and Undrained Shear Strength, Su from VST and Su from CPTu of soil at Zone I and Zone II was presented. |
