Pile foundation model loading device under vertical cyclic load
The invention discloses a pile foundation model loading device under vertical cyclic loading, which comprises a model box and a vertical loading device arranged above the model box, the vertical loading device comprises a cyclic loading device, a central rod piece of the cyclic loading device performs cyclic displacement in the horizontal direction, the cyclic displacement is converted into vertical cyclic displacement through a transmission rod assembly, and the vertical cyclic loading device performs cyclic loading on the central rod piece of the cyclic loading device. The device is used for applying vertical cyclic load to the pile foundation. The device can respectively simulate vertical cyclic loads with different frequencies and amplitudes in the aspect of loads, is more in line with the actual stress-to-damage condition of the pile foundation in the actual situation, can effectively simulate the actual running cyclic load of the high-speed rail train, and is easy to operate, low in test cost, safe and reliable.
本发明公开了一种竖向循环荷载下的桩基础模型加载装置，包括模型箱，设置在模型箱上方的竖向加载装置，竖向加载装置包括循环加载装置，循环加载装置的中心杆件在水平方向上做循环位移，通过传动杆组件转换为竖向循环位移，用于对桩基础施加竖向循环荷载。本发明装置在荷载方面可以分别模拟不同频率、幅值竖向循环荷载，更加符合实际情况中桩基础实际受力至破坏的状况，能有效模拟实际高铁列车行车循环荷载，并且容易操作、试验成本低、安全可靠。
