Recommended Practice for Soft Clay Characterization with a Focus on Settlement and Stability Analysis

Thakur, Vikas / Degago, Samson Abate

Abstract The representativeness and applicability of engineering parameters for geotechnical design is linked to the quality of site characterization. Over the years, a significant effort has been made to improve and refine the in situ testing and soil sampling techniques. Despite these, there is overwhelming evidence that conventional tube and piston samplers are still commonly used for soft soils. Keeping this in mind, the paper aims to guide the readers about the consequences of sample disturbances on strength and deformation behavior of soft clays. In addition, recommendations are made to help them to assign degree of confidence to the soil parameters to be used in settlement and stability analysis.
