| 摘 要： | 针对汶川大地震中产生的在反倾巨厚层状岩体中滑坡的特征,以甘肃武都寨子崖滑坡为实例,通过详细的野外地质调查,结合滑坡区的工程地质环境和面波测试成果,综合分析反倾巨厚层状岩质边坡中形成滑坡的条件,研究其特征和演化机制。不发育结构面、尤其不发育缓倾坡外结构面时此类边坡不具备产生重力滑坡的条件;此类斜坡在仅有水平地震力时同样不易形成滑坡,双向地震力共同作用时易产生地震滑坡。

| Abstract: | To aim at the characteristics of earthquake-induced landslide in heavy layer and antidip stratified rock slope which occurred in the Wenchuan great earthquake,with the Zhaiziya landslide located in Wudu of Guansu province,as the example, the forming conditions of the landslide in antidip stratified rock slope are analyzed through detailed field geological survey data.The characteristics and mechanism of the landslide are discussed combining the engineering geological environment and result of surface wave t... |
