Additional Information:
The soldier piles are 8' o.c. retaining a 12' high level
granular backfill (no surcharge). The lagging is concrete planks with free draining capabilities. The soldier piles will have tie-backs at 1.5' below grade on each pile. The
piles will be about 5 feet into soil then...
Can soldier piles that are socketed 5 feet into bedrock
(HP 10 in 18 in. dia. sockets ) be backfilled with
granular fill in the socket or do they have to be concrete
filled? If so ,how to determine the base capacity?
