There is no practicable laboratory procedure for the determination of compressibility characteristics of cohesionless soils because of the difficulty of sampling of these soils. Therefore, settlement of cohesionless soils may be estimated by a semi-empirical method, based on the results of SCPT, DCPT, or PLT. 1. Schmertmann’s Method for Settlement of Cohesionless Soils: Schmertmann (1970) […]
