近几年,埋入式抗滑桩由于其自身的特点而在边坡支护中得到广泛应用,成为边坡支护的一种主要支护方式。静力情况下,埋入式抗滑桩的研究已经较为成熟,动力作用下的研究目前还较少。设计完成了边坡振动台大型模型试验,通过输入不同类型、幅值、频率的地震波和白噪声激励,探讨地震作用下埋入式抗滑桩模型边坡的动力特性与振动响应规律以及地震动参数对动力特性和动力响应的影响。然后对此模型进行了数值模拟,得出了一些有意义的结论,能够更好地指导边坡抗震设计,有广泛的应用前景。
In recent years, embedded anti-slide piles have been widely used in slope support because of their own characteristics and become a major support way for slope support. Under static conditions, the research on embedded anti-slide piles has been relatively mature, and the research under dynamic force is still less. The large-scale model test of slope shaking table is completed. By inputting seismic waves of different types, amplitudes and frequencies, the dynamic characteristics and the vibration response of the embedded anti-slide pile model under seismic action are discussed. Influence of Parameters on Dynamic Characteristics and Dynamic Response. Then the numerical simulation of the model is carried out, and some meaningful conclusions are drawn. It can better guide the design of slope seismic design and has a wide range of application prospects.
