PROBLEM TO BE SOLVED: To equalize the settling quantity of a loading plate even when the rigidity of the loading plate is low. SOLUTION: In this load testing equipment 10, foundation concrete 14 is allowed to subside while the ground 12 is compressed and deformed by allowing load to act on the foundation concrete 14 in a vertical lower direction by a plurality of hydraulic jacks 20. Herein, a control device 38 controls the load allowed to act on the foundation concrete 14 at each hydraulic jack 20 to which each of hydraulic pumps 32 is connected. Further, the hydraulic jack 20, which is arranged at a place where the subsiding quantity of the foundation concrete 14 is small, increases the load allowed to act on the foundation concrete 14. Accordingly, even when the rigidity of the foundation concrete 14 is low, the subsiding quantity of the foundation concrete 14 is equalized. COPYRIGHT: (C)2011,JPO&INPIT
