GROUND LIQUEFACTION EVALUATION METHOD
PROBLEM TO BE SOLVED: To provide a ground liquefaction evaluation method capable of evaluating liquefaction strength with high accuracy.SOLUTION: In a ground liquefaction evaluation method which evaluates liquefaction strength of the ground 1 of an evaluation object, one measurement point T is set in the ground 1, and an underground acceleration meter 11 and an underground pore pressure meter 12 are inserted to a predetermined depth at the measurement point T. The evaluation method evaluates liquefaction strength of the ground on the basis of data obtained in a manner that: measures changes in accelerations and pore pressure in the ground 1 with the ground 1 oscillated by a vibration exciter 25; and collects data on the accelerations and pore pressure having different magnitudes with the ground 1 oscillated while sequentially moving the vibration exciter 25 to a plurality of oscillation points in a direction away from the measurement point T.SELECTED DRAWING: Figure 1
