【摘要】 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。更多还原

【Abstract】 In recent years,due to its own characteristics in the slope support,the embedded anti-slide pile has been widely applied,and it has become the main way of the slope support.In the static case,the research of the embedded anti-slide pile has already been relatively mature,but the research in dynamic action is still less.The design of shaking table model tests on a slope is completed by inputting different types,frequencies,amplitudes of seismic waves and white noise excitation.The dynamic characteristics and regularity of dynamic response of embedded anti slide pile under the action of earthquake are discussed.The influence of the motion parameters on the dynamic characteristics and responses is investigated.And then this model is simulated,and some meaningful conclusions are drawn to better guide slope seismic design.The embedded anti-slide pile has a wide range of application prospect.更多还原
