PROBLEM TO BE SOLVED: To provide a method for analyzing a pile load test capable of analyzing even when a conventional unloading method is not applicable. SOLUTION: The method for analyzing a pile load test obtains the relationship between a static pile load and displacement using measurement data obtained when the pile is loaded by a loader 1. A fixed speed period having a substantially constant pile head speed is extracted from the relationship between a load time and a pile head speed on the measurement data. The relationship between the load and the pile head displacement on the measurement data corresponding to the fixed speed period is used as an initial slop expressing the relationship between the static pile load and the displacement in the pile load initial part. This line extends and crosses a line expressing the relationship between a ground resistance, obtained by subtracting an pile intertia force from the pile load, and the displacement. From the cross point, this line expresses the relationship between the static load and the displacement, instead of the relationship between the ground resistance and the displacement.
