Settlement and piezometer data from construction of fills on Route I-291 in South Windsor, CT is analyzed for total settlement and coefficient of consolidation. The results are compared with values analyzed from projects at other locations along the lower Connecticut River Valley at which fills were built over varved clay. The present analysis shows the wick drains to be at least as effective as sand drains and there are no detectable adverse effects from vibrating the drains into place. The amount of settlement indicates that the varved clay is overconsolidated.
