CALCULATION METHOD OF EXTRACTION RESISTANCE FORCE OF PILE WITH NODE USING BEARING FORCE ACTING ON INCLINED FACE OF EXPANDED DIAMETER PART, CALCULATION METHOD OF PUSHING-IN RESISTANCE FORCE, DESIGN METHOD OF PILE WITH NODE AND PILE WITH NODE

摘要

PROBLEM TO BE SOLVED: To provide a further highly accurate calculation method of the extraction resistance force of a expanded diameter part for reducing cost and securing safety.;SOLUTION: This method calculates the extraction resistance force of a pile 1 with a node having the expanded diameter parts 3 and 4 including an upper side inclined face 8 inclined so that a diameter becomes large toward the lower side; and calculates a limit extraction resistance force shared by the upper side inclined face 8 on the basis of the product of of the horizontal projection area of the upper side inclined face 8 and a component in the vertical direction of a limit bearing force degree.;COPYRIGHT: (C)2007,JPO&INPIT
