Abstract
This paper presents an investigation of the effects of the properties of reconstituted granular soils on the relationship between CPT cone resistance (qc) and friction angle. The results from a large number of calibration chamber tests conducted at a number of stress levels involving soils with varying shapes, compressibility and mineralogy are presented. The paper also provides data recorded in a parallel series of investigations into the mechanical properties of the granular soils employed in the chamber tests. It is shown that the nature of granular deposits has a strong influence on the relationship between qc and relative density, and that there is a near linear relationship between the cone resistance and the critical state friction angle for sands reconstituted at a given density and stress level.
