土层球根锚杆在滑坡治理中的应用

镇江五峰山长江大跨越塔基滑坡治理工程采用土层球根错杆成功地对多处滑坡进行了治理，取得明显的技术经济效益。现场试验表明，球根错杆具有较高的承载能力。文中对爆破扩孔效果、球根锚杆抗拔能力以及治理滑坡采用的四种工程布置作了介绍。

Application of Earth Anchor with Squibbing in Landslide Control

Earth anchors with squibbing have been used in the landslide control works Of Wu Feng Mountain where locatal the foundation of transmission tower crossing over Yangtze River in Zhenjiang city, China. The technique of using earth anchors gained remarkable economical benefit. The field experiment shows that the earth anchor has relatively high bearing capacity and is simple in construction. The effectiveness in expansion of hole by explosion,the tensile load capacity of earth anchor with squibbing and the arrangements of earth anchors are promed in this paper.
