To verify the mathematical model of ELPLA for computing the immediate (elastic) settlement under a rectangular loaded area on layered subsoil, the immediate settlement of saturated clay layers under a rectangular loaded area calculated by Graig (1978) (Example 6.4, page 175) is compared with that obtained by ELPLA.
Janbu/ Bjerrum/ Kjaernsli (1956) presented a solution for the average settlement under an area carrying a uniform pressure q [kN/m2] on the surface of a limited soil layer using dimensionless factors. Factors are determined for Poisson’s ratio equal to νs = 0.5 [-].
