| 摘 要： | 针对川东华蓥山地区赵子秀山出现大范围的斜坡变形迹象,运用地质雷达方法,查明了地裂缝的延伸深度及影响范围.通过物理模拟方法,对该斜坡演化模式进行模拟分析.研究表明,地裂缝等岩体变形破坏现象的出现是中陡反倾层状体边坡的典型演化模式,即地裂缝的产生是与层状岩体倾倒变形阶段及向滑移破坏阶段过渡过程中相伴生的,滑坡的产生是一个倾倒变形阶段的中止,并且有利于其上部的斜坡岩体继续变形至下一次滑坡或崩塌破坏.可见近期的山体开采对斜坡变形演化的进程具有明显的影响,将促进变形过程的进一步发展.

| Abstract: | Aiming at the large scale slope deformation appeared in Zhaozixiu maintain region of east Sichuan,we investigated the extension depth and affecting scope of ground fissures by using the geological radar.In addition,we studied the slope evolution model using physical modeling.The result shows that rock mass deformation failure such as ground fissure etc.is the typical evolvement model of anti-dip layered rock mass slope with the dip angle being middle to very steep.The ground fissures are formed accompanied ... |
