连霍高速K4189+500段东侧崩滑体稳定性分析
|
摘要
阐述了崩滑体特征及地质环境条件,对崩滑体变形情况及稳定性进行了分析,分析表明崩滑体处于临界状态。稳定性分析认为锁固段支撑了1#强变形区,崩滑体暂未形成贯通的破坏面,崩滑体未出现整体破坏,但崩滑体处于不稳定状态。在保证连霍高速及周边安全的前提下,设计了快速消危措施,通过对锁固段爆破,起动崩滑体,消除了崩滑体的影响。
Features and geological conditions of the landslide are described. Deformation and stability are analyzed. Analysis shows that the landslide is in a critical state and the locking section support 1~# strong deformation zone. Landslide has not yet formed through surface. There is no large-scale slide in this time. But the landslide is in a state of flux. Under the safety of Lianyungang-Huoerguosi highway,measures of eliminating risk are designed, measures is to blow up the locking section, start of landslide,and eliminate the risk factors.
