Static load test of pile foundation is usually carried out after the installation of pile foundation is completed to verify the design bearing capacity of pile foundation and determine the actual bearing capacity. When conducting static load test of pile foundation, a gradually increasing vertical load will be applied to the top of the pile, and the deformation of pile foundation will be obtained by measuring the settlement or strain of the pile body. At the same time, the reaction force at the top of the pile will be measured, and the bearing capacity and deformation performance of pile foundation will be calculated based on these data.
