Deformation Control Of The Dug Hole Belled Pile End Bearing Capacity Pilot Study

Though analog experiment and computer finite element analysis, this essay studies the vertical bearing capacity of man-made pile with bulb shaped base. Then through the analog experiment and theoretical analysis, consulting the scholar's research findings, the calculation formula of pile end bearing capacity that bases on Mindlin solution is deduced, and the parameter-deformation modulus and the criterion of settlement is defined and validating t he really engineering,proving the method of deforming controlling the pile end vertical bearing capacity is better than the method of strength controlling.
