I think you might be right; i'm going to do a few calcs but not sure what to use for the coefficient of secondary compression (Ca) yet! I guess we need some oedometer tests on re-compacted fills?
The liquid limit of the proposed 5m of clay fill typically ranges from 41-47% with one result (of 8) at 57. Plasticity indices all ranged between 24 and 27%. N values in the Till were 12-17 below the proposed embankment (upper soft layers will be removed). The housing will be piled due to the...
The underlying strata is typical firm clay (glacial till / weathered Charmouth Mudstone), near surface soft materials will be removed and a granular drainage blanket installed, and the piles will need to be designed accordingly. The fill will be variable glacial till / arisings from adjacent...
Hi. I have a proposed residential site where up to 5m of clay fill (glacial till, from various new and old stockpiles) is proposed to be compacted at 95% maximum dry density on a 300mm granular drainage layer. The houses will be piled however is long term settlement of the fill itself an issue...
