文章结合贵州乌江沙沱水电站工程建基面上由于裂隙与倾向下游的岩层层面互相切割导致岩体整体松动的治理案例,详细阐述了预应力锚索在解决坝基深层抗滑稳定中的锚索设计方法、锚索布置方案、施工技术、施工流程及关键工艺参数。经分析可知与钢管桩和钢筋桩等处理措施相比,预应力锚索应用于坝基深层抗滑稳定中施工工程量少很多,同时能在最大限度上保证坝体的完整性,采用该技术能做到施工工序明确、施工质量有保证,工期更加独立可控,抗干扰性强,造价较传统措施要低30%~45%,总体经济效果明显。
文章結閤貴州烏江沙沱水電站工程建基麵上由于裂隙與傾嚮下遊的巖層層麵互相切割導緻巖體整體鬆動的治理案例,詳細闡述瞭預應力錨索在解決壩基深層抗滑穩定中的錨索設計方法、錨索佈置方案、施工技術、施工流程及關鍵工藝參數。經分析可知與鋼管樁和鋼觔樁等處理措施相比,預應力錨索應用于壩基深層抗滑穩定中施工工程量少很多,同時能在最大限度上保證壩體的完整性,採用該技術能做到施工工序明確、施工質量有保證,工期更加獨立可控,抗榦擾性彊,造價較傳統措施要低30%~45%,總體經濟效果明顯。

The pre-stressed anchor cables which were effective in improving the stability of rock slopes and convenience construction. There is a crack which would cause the slip on the dam foundation in Shatuo hydropower station in Guizhou province. Based on analyzing the treatment to dealing with the crack, how to design and where to arrange the pre-stressed anchorage cables, the main technological parameters, construction technique, quality control and management are provided. A conclusion could be drawn through the paper that the adoption of pre-stressed anchor cable to reinforce the dam could improve the stress conditions in the dam body, enhance the integrity of dam, close the horizontal cracks and has the advantages of easy construction, construction period is independence from other factors, normal operation of power station. The cost of pre-stressed anchor cable was 30 % to 45 % less than traditional treatments so that it is one of effective and reliable methods of reinforcing dangerous dams which will be covered in the similar engineering.
