Coupling loading model test device of pedestal pile foundation and use method
The invention discloses a coupling loading model test device of an expanded bore pile foundation and a use method. According to the coupling loading model test device for the expanded-base pile foundation, vertical propelling force is transmitted to a vertical loading bottom plate, and the vertical loading bottom plate provides the vertical propelling force for an expanded-base pile, so that vertical self-weight is simulated; horizontal propulsive force is provided for the expanded-base foundation pile through the hydraulic cylinder, and pressure data transmitted back by the tension and pressure sensor and instructions of the control system are combined to control the output load, so that the random wind load effect is simulated. The device is wide in application range, high in automation degree and capable of being accurately controlled, a simulation test of the wind power expanded bore pile foundation under random wind load and vertical self-weight coupling loading can be achieved, control over the random wind load and the vertical self-weight can be accurately achieved, and the test efficiency is improved. Simulation of the pedestal pile foundation under the action of random loads at different wind speeds can be carried out in foundation soil with different characteristics.
本发明公开了一种扩底桩基础的耦合加载模型试验装置及使用方法。一种扩底桩基础的耦合加载模型试验装置将竖向推进力传递到竖向加载底板，竖向加载底板向扩底基桩提供竖向的推进力，从而模拟竖向自重；通过液压缸向扩底基桩提供水平推进力，通过拉压力传感器传回的压力数据与控制系统指令联合控制输出荷载大小，从而模拟随机风载作用。本发明适用范围广，自动化程度高，可精确控制，能够实现风电扩底桩基础在随机风载和竖向自重耦合加载下的模拟试验，能精准实现随机风载与竖向自重的控制，可以在不同特性的基土中进行在不同风速的随机荷载作用下扩底桩基础的模拟。
