PROBLEM TO BE SOLVED: To provide a method for conducting a loading test at the front end of a cast-in-place pile, which requires only simple test facilities, drastically reduces costs, and facilitates works. ;SOLUTION: In construction of a cast-in-place pile, a casing 1 which has been penetrated into a predetermined depth in the ground, is left without pulling out the same. After discharging excavated earth and sand in the casing 1, a loading stand frame 2 is attached to an upper end of the casing 1, and a loading rod 3 is connected to the loading stand frame 2 via a loading jack 5, whereby a loading plate 4 attached to a lower end of the loading rod 3 is inserted into the casing 1 until the plate 4 makes contact with a hole bottom. Then, a predetermined load is applied to the hole bottom via the loading rod 3 and the loading plate 4 by means of the loading jack 5, and a settled amount of the loading rod 3 which is settled together with the hole bottom, is measured based on the load, by a measuring means 7a.;COPYRIGHT: (C)2001,JPO
