摘要： Provided are a device for simulating a full-scale pile-sinking process of a static pressure pile by air bag preloading and a test method thereof. The device comprises a frame, a beam, a hydraulic jack, a model box, a model pile, a first sand layer, an undisturbed soil mass, a second sand layer, a rubber pad, a forcing air bag, a counter-force steel plate, a model box top cover, a forcing pipe, a pressure relief pipe, a steel casing and a control system. The first sand layer, the undisturbed soil mass, the second sand layer, the rubber pad, the forcing air bag and the counter-force steel plate are laid in the model box in sequence; and the steel casing passes through the model box top cover, the counter-force steel plate, the forcing air bag and the rubber pad in sequence and then reaches a bottom portion of the second sand layer.

摘要： Provided are a testing apparatus for a pile end settlement of a rock-socketed driven PHC tube pile and an installation method thereof. The testing apparatus comprises a PHC tube pile, two measuring tubes, a cross pile tip, a pile tip steel plate, a fixer fixed in the PHC tube pile, a perforated steel plate located at a pile top of the PHC tube pile and a jack pressed on the perforated steel plate. The two measuring tubes are symmetrically arranged, the fixer is provided with two first measuring tube outlet holes, and the two measuring tubes respectively pass through the first measuring tube outlet holes of the fixer; and the perforated steel plate is also provided with two second measuring tube outlet holes, and the two measuring tubes respectively pass through the second measuring tube outlet holes of the perforated steel plate.
