基于简化纽马克位移模型的地震滑坡岩土体强度参数研究
|
摘要
本文以2008年汶川M_S8.0地震的烈度数据为基础,采用简化纽马克法对四川省青川县不同岩组的岩土体强度参数组合所对应的滑坡位移进行计算得到滑坡危险性等级图,并以计算得到的预测滑坡区与实际调查的滑坡数据的吻合度作为评价标准,对研究区内岩土体强度参数进行分析。分析结果表明,研究区大部分区域岩组的岩土体强度参数的合理取值区间与《工程岩体分级标准GB 50218—94》建议的参数取值范围基本一致,而本文在此基础上所确定的取值结果,在一定程度上可以提高地震滑坡危险性评估的精度。
According to intensity data from the 2008 Wenchuan M_S8.0 earthquake,the simplified Newmark method was used to calculate the landslide displacement corresponding to the combination of rock-soil strength parameters of different rock groups in the Qingchuan county,Sichuan Province. Taking the goodness-of-fit between the actual and the predicted landslide data as the evaluation criteria,we analyzed the rock-soil strength parameters in the studied region. The results showed that the reasonable value ranges of rock-soil strength parameters of rock groups in most of the studied region were basically consistent with the ranges of recommended parameters of Standard for Engineering Classification of Rock Masses GB 50218—94.Referring to the parameters ranges determined in this paper,the evaluation accuracy of the earthquake landslide susceptibility level can be improved to some extent.
