WebThe method of disturbing the soil and the magnitude of disturbance significantly influence the magnitude of sand-ageing effects. This paper provides the first data on sand ageing following the installation of displacement rammed aggregate piers. In this study, CPT and DMT were performed both immediately before and after the installation of piers. WebGeopier® rigid inclusion systems are ground improvement elements used to transfer loads through weak, compressible soils and into deeper competent bearing soils. These systems are ideal for settlement control of heavy structures underlain by thick deposits of compressible soils (organics, soft clays, and loose sands).
