Analysis on Selection of Tip-Structure of Steel Tubular Pile

Abstract:

Three types of tip-structure include open-end, semi-closed and full close are tested to verify the feasibility of improving the ultimate bearing capacity in stiff clay layer. Driving pile trials are carried out in the site. This paper presents the analysis of set, driving stresses and bearing capacity according to the survey of set, driving monitoring, high strain dynamic test and the axial compression static test. It is proved that the closed end is the most feasible structure in stiff clay layer.
