摘要
介绍使用预应力锚索加固大型边坡工程的实例。加固施工采用由瑞典Ａｔ－ｌａｓ公司ＭａｓｔａｎｇＡ－６６全自动、全方位、全液压钻机，干法造孔钻进时效达到百米，有效地控制了施工中孔壁坍塌和边坡失稳。钻孔的偏斜度低于３％。
Prestressed anchor rope used in consolidation engineering design and construction for a large slope is introduced by an engineering example. A Mastang A 66CB drill made in Atlas Copco.Sweden is used in the consolidation construction engineering, which is all automation,all direction, and full hydraulic pressure drilling with speed of over 100m/h. In the construction, hole wall callapse and slope unsteadiness have been controlled effectively. Deflected oblique angles of drill holes are lower than 3%. Anchor stress has been ensured to come to requested greatest stress value for design.
