Pile foundation model loading device under cyclic load
The invention discloses a pile foundation model loading device under a cyclic load. The pile foundation model loading device comprises a main frame, a counter-force frame at the top of the main frame,a horizontal steel frame with fixed pulleys at the top of the counter-force frame, a horizontal cross beam at the side portion of the counter-force frame, a vertical cyclic loading system on the leftside of the main structure, a horizontal cyclic loading system on the right side of the main structure, a first counterweight, a second counterweight, a dynamometer and a displacement sensor; and thedynamometer is used for measuring the vertical cyclic load value and the horizontal cyclic load value, the displacement sensor can detect the horizontal displacement and the vertical displacement ofa pile foundation, the left side of a model groove is also provided with a controllable drainage partition plate, so that pore water is conveniently discharged, and a pulley is arranged at the bottomof a main groove body to facilitate the overall movement of a model box. The device overcomes the limitation of single static loading, can more effectively simulate the load-bearing state of the pilefoundation under real conditions, and is simple and easy to operate.
本发明公开了一种循环荷载下的桩基模型加载装置，包括一个主体框架、主体框架顶部的反力架、反力架顶部的带定滑轮的水平钢架、反力架侧部的水平横梁、主体结构左侧的竖向循环加载系统、右侧的水平循环加载系统、第一配重砝及第二配重砝码、测力计、位移传感器；测力计用于测量竖向循环荷载值及水平循环荷载值，位移传感器可检测桩基础的水平位移与竖向位移，模型槽左侧还设置可控排水隔板，便于孔隙水的排出，在主槽体底部设置滑轮，便于模型箱的整体移动；本发明装置解决了单一静力加载的局限性，能够更有效的模拟出真实情况下桩基础的受荷状态，且装置简单，易于操作。
