| 摘 要： | 宝兴县潘族组崩塌位于＂5.12＂汶川地震重灾区四川省宝兴县,地震诱发多处危岩体崩塌失稳,造成崩塌滚石地质灾害。受地震效应作用,危岩体后缘拉裂隙逐渐被贯通,形成抛射型崩塌模式。滚石运动路径主要受滚石形状、起始运动方式、坡面特征和坡体形态等因素的影响。通过调查滚石与坡面碰撞留下的地质痕迹,真实复原了滚石运动路径。依据坡度、...

| Abstract: | The Panzuzu collapse is located in thetown of Baoxing,Sichuan Province,which is a heavier disaster area in 5.12 Wenchuan earthquake.The earthquake brought out several dangerous rock avalanches instability,and caused the collapse of rolling stones geological disasters.Influenced by earthquake,the dangerous rock edge crack is gradually be well versed during the earthquake,and formed shattering-ejection mode.The movement path of rolling stone is mainly influenced by the shape of rolling stone,starting movement... |
