摘要:
掌握滑坡运动学特征，针对运动学特征提出防治措施是减轻滑坡灾害的关键。在野外调查资料与土工试验的基础上，基于颗粒流离散元方法，研究了西吉县兴平乡堡湾村下马达子滑坡的发生过程，探索了黄土地震液化型滑坡的发生机理和运动规律，通过与未液化的地震滑坡进行对比，分析了地震液化对滑坡运动的影响，归纳地震液化型滑坡的运动学特征。具体分析结论如下：（1）液化模型较未液化模型更容易发生失稳破坏，速度更大、滑距更远、破坏性更强；（2）无论是液化模型还是未液化模型，坡肩位置都是地震滑坡发生失稳的关键部位；（3）斜坡液化后，在液化区附近的区域滑体会推动和冲击下部滑坡体，造成斜坡更大面积的失稳，这是液化型地震滑坡具有低角度，强破坏力特征的原因之一。
Abstract:
Mastering the kinematic characteristics of landslide and proposing prevention measures according to the kinematic characteristics are the keys to reduce landslide disasters. On the basis of field investigation data and geotechnical test, the occurrence process of Xiamadazi landslide in Baowan village, Xingping township, Xiji county was studied by using particle flow discrete element method, and the occurrence mechanism and motion law of loess seismic liquefaction landslide were explored. By comparing with the seismic landslide without liquefaction, the influence of seismic liquefaction on landslide motion was analyzed, and the kinematic characteristics of seismic liquefaction landslide were summarized. The conclusions are as follows:(1)Liquefaction model is more prone to instability failure than non-liquefaction model, with greater speed, farther sliding distance and stronger destructiveness;(2)Whether the liquefaction model or the non-liquefaction model, the slope shoulder position is the key part of the instability of seismic landslide;(3)After the slope is liquefied, the regional landslide near the liquefied area experiences to push and impact the lower landslide body, resulting in a larger area of instability of the slope, which is one of the reasons for the characteristics of liquefied seismic landslide with low angle and strong destructive force.
