Shear Skin Transfer of Concrete Drilled Piles Testing and Modelling

Popis výsledku v původním jazyce

A semi analytical procedure was carried out to compute a settlement and normal force distribution of the axially loaded concrete drilled pile. The deformation variant of the solution was selected. The pile-soil interface is modeled using physical nonlinear soil springs. The shear peak forces are limited. The value of the force depends on the vertical earth pressure and on the quality of the soil pile interface in the investigated point. For the shear response of the soil layer the known analytical solution is adopted. From the comparison of the axial force measurement within the pile and the measurement of the settlement the fatal influence of the shear force transfer is evident. Once the peak value of the skin shear is developed along a large region the settlement incredibly increases. The good agreement between the computed and measured values was obtained. The problem is that too many parameters enter the calculation which makes difficult their verification in situ.
