Static load testing is an in situ type of load testing used in geotechnical investigation to determine the bearing capacity of deep foundations prior to the construction of a building. It differs from the statnamic load test and dynamic load testing in that the pressure applied to the pile is slower.[1][2] Static load testings are performed in order to measure a design's axial tension or axial compression. It can also be used to measure its deflected shape under lateral load.[3]
