Title: MODIFICATION OF SAND-DRAIN PRINCIPLE FOR PRESSURE RELIEF IN STABILIZING EMBANKMENT FOUNDATION
Accession Number: 00232496
Record Type: Component
Abstract: A 20-FOOT DOUBLE EMBANKMENT ON THE PORTLAND-SALEM EXPRESSWAY CROSSES A PEATY, POORLY DRAINED AREA. THE APPLICATION OF THE SAND-DRAIN PRINCIPLE TO THE PERIMETER OF THE EMBANKMENT AREA PROVIDES OUTLETS FOR THE FREE WATER UNDER PRESSURE OF THE EMBANKMENT LOADS AND PERMITS ACCELERATED CONSOLIDATION OF THE FOUNDATION SOILS UNDER THESE LOADS WITHOUT LATERAL FLOW BEYOND THE TOES OF THE EMBANKMENT. TWO BRIDGE APPROACH AREAS IN THIS FILL, NOT PROTECTED BY PRESSURE RELIEF DRAINS, SHOWED SIGNS OF LATERAL FLOW THROUGH SLIGHT HORIZONTAL MOVEMENTS OF BRIDGE PILING. /AUTHOR/
