摘要：

Estimating the deformation modulus of gravelly soils is a challenging task. The estimate of deformation modulus of cohessionless soils in general relies on availability of correlation between in situ test parameters and deformation modulus back-calculated from field results of pressure settlement relationship based on plate load or footing load tests or observed settlement records. However, such a correlation is rare for gravelly soils. Even if it exists, the correlation is usually constrained with few limitations due to field testing problems associated with presence of gravel size particles. The aim of this paper is to develop a new correlation between deformation modulus of gravelly soils and results of dynamic cone penetration tests. The correlation relies on results of footing load tests carried out in a reclaimed site in Alexandria, Egypt, side by side to dynamic cone penetration tests. The developed correlation is reinforced by settlement records for structures on gravelly soils from literature. (C) 2013 Ain Shams University. Production and hosting by Elsevier B.V.
