Investigations to determine the bedding of double-T piles in soil – Part I: fundamentals and in-situ-tests
The main part of the load transfer of combined sheet pile walls is performed by the king piles embedded in the soil. At present, however, the calculation for combined walls in the final state is carried out without considering the resistance of the soil to twisting or buckling of the king piles. With attention to the valid standards, the consideration of the bedding becomes necessary for the combined verification of flexural buckling and torsional flexural buckling in order to en-able an economic design against stability failure. The bedding of king piles in cohesive soil differs from that in non-cohesive soil and has been investigated by laboratory and large field tests. The results of the field tests of the FOSTA/AiF project P1327 with the aim to optimize the stability procedure of combined walls will be presented in Part I. The torsional spring stiffness in sand is about seven times greater than in clay. Ne-vertheless, the resistance to twisting in cohesive soil is not negligible.
