2008年汶川地震前的中国大陆地震单体滑坡与边坡地震响应
Earthquake- triggered individual landslides and slope seismic responses across mainland China before the 2008 Wenchuan earthquake
【摘要】 承接"2008年汶川地震前的中国大陆地震滑坡研究"一文,对2008年汶川地震前的典型单体地震滑坡或边坡地震动响应开展综述。包括:1)工程地质分析,包括真实地震滑坡分析和地震动条件下边坡分析;2)传统力学计算分析方法,包括Newmark方法与极限平衡方法等;3)有限元分析,包括Geostudio平台与FLAC平台等;4)离散元分析,主要包括UDEC等离散元程序在地震滑坡领域的应用;5)物理模型试验。
【Abstract】 This article focuses on earthquake-triggered individual landslides and slope seismic responses,and is the continuation of"Earthquake-triggered Landslides across Mainland China Before the 2008 Wenchuan Earthquake". Individual landslides or stability of slopes under seismic forces in cases before the 2008 Wenchuan earthquake are reviewed in detail using the following approaches:1) geological analysis of real earthquake- triggered landslides or slope stability analysis under seismic forces; 2) conventional computational mechanics analysis,including the Newmark method and ultimate equilibrium method; 3) finite element analyses,such as Geo Studio and FLAC platforms; 4) discrete element analyses,such as UDEC and other programs applied in the filed of seismic landslides; and 5) physical models. This review aims to provide references for similar studies in the future.
