ON THE EFFECTIVENESS OF SAND DRAINS

THE DETRIMENTAL EFFECTS OF DRIVING SAND DRAINS IN SENSITIVE SOILS ARE DISCUSSED. SEVERAL CASE RECORDS OF THE BEHAVIOUR OF EMBANKMENTS ON SUCH SOILS ARE ANALYZED. IT IS CONCLUDED THAT IF A CAREFUL FOUNDATION INVESTIGATION INDICATES THE DESIRABILITY OF INCREASING THE RATE OF PRIMARY CONSOLIDATION, NON-DISPLACEMENT SAND DRAINS SHOULD BE USED. IT IS ALSO SHOWN THAT SAND DRAINS OF ANY TYPE ARE OF LITTLE OR NO VALUE IN SOILS THAT EXHIBIT SUBSTANTIAL SECONDARY SETTLEMENTS. /CGRA/
