Experimental Sand Drain Study Napa. River Project, Mare Island 10-Sol-37-Pm 7.1/7.4
The results of a special study, involving the use of sand drains to aid the consolidation of weak compressible soils, are presented. Settlements, excess hydrostatic pressures, strength and moisture changes, instrumentation, movements, and failures are discussed. It was found that actual consolidation time lagged behind the theoretical predictions in the sand drain areas. This lag could be predicted by theoretical consideration of the disturbance caused by the displacement method of sand drain installation. High excess hydrostatic pressures, caused by the sand drain installation contributed to failure of the embankment in the sand drain area. (Author)
