ABSTRACT
The press-in method is a piling method using a hydraulic jacking force to install a prefabricated pile. Its applicability in hard ground has been enhanced by the relatively recent development of its branch techniques such as the press-in with auger and the rotary cutting press-in (RCP). In RCP, a tubular pile equipped with several cutting teeth on its base is pushed and rotated, so that even concrete or rock can be penetrated through by the pile. The RCP piles are usually used for retaining walls, but are also used for structures where their axial stiffness and capacity are of concern. In this paper, three sets of subsurface information (CPT cone resistance), the piling data of the RCP and the static vertical load test results on the RCP piles with an outer diameter of 508 mm are reported, which were obtained in preparation for the project of updating the quay walls in the World Heritage-listed Canal Ring Area of Amsterdam. In addition, the cone resistance and the vertical capacity are estimated from the piling data obtained during the RCP, and are compared with the results of the CPT and of the load tests.
