Oct 03, 2003· I presume that was a drained angle of internal friction; the sand being placed hydraulically would never be able to achieve this angle (or an active case) until all pore pressure had dissipated (the drained condition). Depending on how much of the backfill was below the adjacent water level, it might never reach this condition.

Search results for: stone column

Two types of stone were used namely small and bigger in size. Results indicate that there is an increase in angle of internal friction and also an increase in the shear strength of soil when stone columns are encased. With stone columns with 50mm dia, an average increase of 7% in shear strength and 4.6 % in angle of internal friction was achieved.
