Discussion on formula for anti pull bearing capacity of DX pile

Yuan Xiyu,He Dexin,Chen Lihong

Strategic Study of CAE 2012, Volume 14, Issue 1,   Pages 69-73

Abstract:

When the DX-pile is under uplift load, the pile-soil interaction consistsof pile shaft resistance and uplift resistance provided by the bells which effectively raises the uplift-pileThe friction resistance along pile shaft friction has been study well and has lots of results, but theproblem of calculating the resistance of bell is still under studied which is the key to DX-pile uplift
