摘　　要：通过总结叶巴滩水电站大坝左右岸缆机平台以上边坡、缆机平台至坝顶边坡锚喷支护的施工经验,介绍了锚杆注浆采用二次清空、先注浆后插杆工艺等细节控制措施,与传统锚杆注浆质量优良率相比,无论在质量控制方面,还是施工进度方面新方法都表现出更大的优势。以细节控制措施在高品质锚杆注浆优良率中的应用为例,介绍了Ⅰ类锚杆比例提升的科技创新和实际应用过程。By summarizing the construction experience of bolt and shotcrete support on the slope above the cable crane platform on the left and right banks of the dam of Yebatan Hydropower Project and the slope from the cable crane platform to the dam crest,the bolt grouting adopts the detailed control measures such as secondary emptying,grouting first and the inserting rod technology.Compared with the excellence rate of the traditional bolt grouting quality,the new method shows greater advantages in both quality control and construction progress.Taking the excellent rate of detail control in high-quality bolt grouting as an example,this paper introduces the scientific and technological innovation and practical application of increasing the proportion of class Ⅰ bolt.
