摘要
以贵州岩溶区某机场高填方边坡滑塌破坏为工程实例,根据边坡的地质勘察资料及现场调查情况,阐述了该高填方边坡滑塌变形破坏特征。根据变形监测的数据,详细分析了滑塌体的空间运行状态、变形破坏过程及变形机制,即下伏地层发生过大沉降变形时,导致了上部土体发生滑塌变形破坏,其特点是以沉降变形为主,兼有明显水平滑移。并介绍了治理措施及治理后的效果。
Taking an airport high embankment in a karst region of Guizhou as an example, its collapse--slide characteristics, space operating mode, mechanism and processing are analyzed by deformation monitored method. It is the conclusion that the large settlement of the bottom strata would lead the upper strata to collapse and to slide. Its characteristics is dramatic decline with obvious level displacement during the collapsing and sliding, and the treatment methods are put forward.
