Pile foundation model loading device for vertical/horizontal cyclic loading
The invention discloses a pile foundation model loading device for vertical/horizontal cyclic loading. The pile foundation model loading device comprises a model box, a counterforce frame which is disposed on the model box, a horizontal rigid frame which is welded to the middle of the counterforce frame on the top and provided with fixed pulleys, a horizontal loading system, a vertical loading system, slide wheels which are disposed at the bottom of the model box, dynamometers which are disposed on a vertical loading device and a horizontal loading device, and a displacement sensor. In a test,by controlling an adjustable-speed motor to rotate a vertical rigid rotating shaft, balance weights are driven to do horizontal circumferential motions, so that vertical cyclic loading and horizontalcyclic loading under different cyclic amplitudes are realized. Compared with the prior art, the pile foundation model loading device overcomes the defect that an existing loading device can only perform monotonous loading, can effectively simulate vertical cyclic loads generated by vehicles to and fro in a bridge pile foundation and horizontal cyclic loads of wind, waves and the like, and is widein application range and convenient to operate.
本发明公开了一种用于竖向/水平循环加载的桩基模型加载装置，包括模型箱、模型箱上的反力架、顶部反力架中间焊接的带定滑轮的水平刚架、水平加载系统、竖向加载系统、板模型箱底部的滑轮、在竖向与水平加载装置上安装的测力计及位移传感器，试验时通过控制调速电机转动竖向刚性转轴，从而带动配重砝码做水平圆周运动，实现不同循环幅值下的竖向循环加载与水平循环加载。与现有技术相比，本发明弥补了现有加载装置只能进行单一加载的缺陷，能够有效的模拟桥梁桩基础中往来车辆产生的竖向循环荷载以及风、波浪等水平循环荷载，且适用范围广、操作便捷。
