<P>PROBLEM TO BE SOLVED: To provide a method for economically actualizing a pile body structure and a foot protection part structure while considering that adhesive force and bearing force favorable to an existing pile works under the conditions of securing integration between the existing pile and a foot protection part. <P>SOLUTION: In a structural specification determining method for the bored pile formed by burying a straight existing pile 1 in a pile hole having a foot protection part 2 formed in the bottom so that the lower end of the existing pile enters into the foot protection part 2, the specification of the pile body and the specification of the foot protection part are determined to satisfy (1) design load≤bearing force determined from ground, and (2) design load≤pile peripheral face adhesive force at foot protection part+pile front end bearing force. <P>COPYRIGHT: (C)2013,JPO&INPIT |
