Abstract

Deformation modulus Ev of sandy deposits subjected to vertical loading was estimated in connection with the use of a pressuremeter. The deformation modulus Epm measured by using pressuremeters was related to deformation modulus Ev backcalculated for the in-situ plate loading tests and from the monitored settlement of structures in which standard penetration test (SPT) blow counts N are known. In order to assess the relationship between Ev and Epm, triaxial tests and small scale pressuremeter tests were performed on laboratory samples of sandy deposits. The ratios Ev/Epm obtained, were found to agree with the SPT blow count N.
