摘要
高陡岩质边坡地形陡峻,特别是强风化花岗岩质边坡,成颗粒泥质状,在强降雨雨水冲刷下,极易崩解有发生滑坡的趋势;岩质边坡坡面节理裂隙发育强烈,坡面岩体被切割成块状,边坡底部会有崩落岩块,局部坡面形成裸露岩腔。稳定性极差,对附近居民生命安全及建筑物都构成威胁。采用锚杆支护策略,可以更好满足边坡治理稳定的需求,经济性、实用性颇高。
The high and steep rock slope has a steep terrain,especially the intensively weathered granite slope,which is in the form of granular mud.It is easy to disintegrate under the strong rainfall and rain wash,and there is a tendency of landslide;the joint fissures on the rock slope surface are developed strongly,the rock mass on the slope surface is cut into blocks,there will be disintegrated rock blocks at the bottom of the slope,and exposed rock cavities will be formed on the partial slope surface.The stability is very poor,which is a threat to the lives of nearby residents and buildings.The adoption of bolt support strategy can better meet the needs of slope control and stability,with high economy and practicability.
