Abstract: The thickness of the residual soils is related to their deposition locations: erosions are severe at the top of hills and the thickness is smaller whereas a thicker deposit can be found in the valleys. This paper presents a case study of the residual soils in Bijie-Weining Expressway construction project in Guizhou Province. The in situ tests, such as, light dynamic penetration test, shear wave velocity test, are performed in the strongly structured residual soils.

Key words: Residual Soil, Dynamic Penetration Test, Shear Wave Velocity
