Abstract
When constructing land reclamations, one aims to ensure that the final soil mass fulfils certain minimal criteria related to shear strength, stiffness and resistance against liquefaction. In general, these characteristics do reflect improvement with increasing density of the soil mass. Quality control of reclamation constructions therefore usually focuses only on: ‘adequate densification’. Such criterion is often translated into technical requirements using a single parameter: the relative density Dr. On site, this parameter is commonly derived indirectly from correlations with the cone penetration resistance qc, making the CPT the main tool for quality control. This paper presents some results of this questionable procedure and of possible alternative methods on land reclamations using calcareous sands.
