This paper deals with the bending of slender precast concrete piles which are driven in segments 10 to 14 m in length and spliced in the field by means of rigid steel couplings. The requirements of the Swedish Building Code for allowable bending of these piles are reviewed and the method of inspecting the bending is described. The inspection is performed by lowering a slope inclinometer through a pipe, which is cast centrically in the pile and attached to special couplings by which access all through the pile is obtained.By the inclinometer the inclination and the direction of the inclination is measured. The results are used for determining the location of the pile in the ground and the bending of the pile. Mathematical expressions for this are derived.In Swedish practice, when judging a pile, the bending of the pile segments is treated separately from the bending of the pile over the pile splices, as the latter involves the question of squareness of the joint couplings in casting. The bending of a segment is judged in terms of change of inclination per metre of pile and of bending radius over the length of the segment. A typical example is given on how to present and evaluate the measuring results.
