边坡支护工程区域质条件复杂多样,采用预应力锚索进行加固处理施工难度大,本文结合仁怀市云帱山深林公园边坡支护工程大型滑坡复杂地层预应力锚索工程实践,着重对复杂地层大口径锚索成孔技术及拉力集中型预应力锚索的施工工艺及特点进行总结,对指导今后类似工程施工有借鉴意义。
The conditions of the slope support engineering are complex and diverse, and it is very difficult to reinforce with the prestressed anchor cable. In this paper, combining with the prestressed anchor cable engineering practice of large-scale landslide complex slope in the Yunlin Mountain Forest Park in Renhuai City, This paper summarizes the construction technology and characteristics of the large-diameter anchor cable for hole formation and the tension-concentrated prestressed anchor cable in complex formations, which has reference significance for guiding the similar project construction in the future.
