摘　　要：以罐滩滑坡为原型,设计、制作下伏软弱层的反倾边坡物理模型,进行模拟试验,研究其动力响应规律,并详细论述了物理模型试验的相似设计、试验方案设计以及模拟试验结果分析。通过对比前、后两种加载方式中各测点加速度峰值与加速度放大系数的关系,得出物理模型的动力响应特征规律。Based on the Prototype of Guantan landslide, the physical model of counter-tilt slope of underlying soft stratum is designed and fabricated to conduct simulation test so as to study its dynamic response rules and the similar design, test scheme design and simulation test results analysis of physical model test are illustrated in detail. Finally, the dynamic response rules of the physical model are obtained through comparing the relationship between the acceleration peak value and acceleration amplification factor of the measuring points in two loading modes.
