摘　　要：文章针对边坡在地震下的破坏形态,构建了四川汶川王家坡边坡模型,采用有限离散元法(简称“FDEM”),对地震作用下边坡的动力响应进行数值模拟。为了验证所采用方法的准确性,将模拟结果与已有文献中的实验数据进行对比,结果表明,FDEM的模拟结果具有较高的可靠性。文章的研究成果对于深入了解边坡在地震作用下的动力响应及其破坏机制具有重要意义。未来研究可进一步探讨其它因素对边坡破坏程度的影响,为滑坡灾害防护工程提供更多的理论支持。This paper focuses on the failure mode of slopes under earthquakes and uses the finite discrete element method(FDEM)to construct a slope model of Wangjiapo in Wenchuan,Sichuan province.The established finite discrete element method is used to numerically simulate the dynamic response of slopes under earthquake action.To verify the accuracy of the adopted method,the simulation results were compared with experimental data in existing literature,and the results showed that the FDEM simulation results have high reliability.The research results of this paper are of great significance for a deeper understanding of the dynamic response and failure mechanism of slopes under earthquake action.Future research can further explore the impact of other influencing factors on the degree of slope failure.It provides more theoretical support for landslide disaster prevention engineering.
