Abstract
When the DX-pile is under uplift load, the pile-soil interaction consists of pile shaft resistance and uplift resistance provided by the bells which effectively raises the uplift-pile ultimate bearing capacity. The friction resistance along pile shaft friction has been study well and has lots of results, but the problem of calculating the resistance of bell is still under studied which is the key to DX-pile uplift capacity. This paper calculates the bearing capacity of DX-pile and compares it with the measured value on the basis of a project to discuss and study these calculation methods, and a new method of calculation is also proposed.
