Abstract: 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.

Abstract: A system and method for monitoring an earth pressure and displacement of a miniature steel pipe pile body. Sensor installation holes are drilled at predetermined positions outside the steel pipe pile body and sensor metal protective shell with a thickness slightly lower than that of the XY-TY02A resistance-type miniature earth pressure gauge is welded on the steel pipe pile body. The XY-TY02A resistance-type miniature earth pressure gauges are stuck on the steel pipe pile body. The transmission line of the XY-TY02A resistance-type miniature earth pressure gauges passes through the sensor installation holes and are connected to data acquisition system. The reflective sheet base is welded at the preset position of the miniature steel pipe pile and the reflective sheet is attached to the reflective sheet base to realize displacement monitoring.
