摘要
通过对云南省元绿(元阳至绿春)二级公路LK7+800—LK8+030右侧路堑边坡预应力锚索框架失效的现场调查,从工程地质、变形迹象、现场监测数据等多方面对锚索框架的失效原因进行分析,然后提出软弱破碎岩石边坡中预应力锚索框架的适用性,并提出合理的处治对策,可为预应力锚索框架设计提供借鉴。
Based on the field investigation of the failing prestressed anchor cable frame for the right side cutting slope in Yunnan Yuanyang- Lvchun secondary road LK7 ＋ 800- LK8 ＋ 030,failure causes of anchor cable frame were analyzed fromsuch aspects as engineering geology,deformation signs and field monitoring data,the applicability of prestressed anchor cable frame for weak and broken rock slope and some reasonable treatment measures were put forward,which could provide a reference for prestressed anchor cable frame design.
