摘要
土层锚杆在我国深基坑支挡、边坡加固、滑坡整治、水池抗浮、挡墙锚固和结构抗倾覆等工程中应用日益广泛。以溪洛渡水电站左右岸出线竖井上段覆盖层段开挖施工为依据,对不同地质条件下的土体锚固技术进行论证及施工实践验证,将岩石锚固技术很好地融入到复杂地质情况下的土体加固施工中,改变了传统的土体加固技术,在钻孔机具的选择、钻孔技术研究以及相关加固技术等综合运用方面进行了初步探索,形成了一定的技术成果。
The soil layer anchor rod is increasingly applied in foundation pit excavation retaining,slope reinforcement,landslide remediation,pool of anti-floating,anchored retaining wall and anti-overturning structure projects in China.For the upper overburden layer excavation of left and right outlet shaft of Xiluodu Hydropower Station,the anchoring technologies for different soil geological conditions were studied and verified by practice.After integrating rock anchor technology into soil reinforcement construction,a set of construction technology including drilling machine choice,drilling and reinforcement and its application was developed.The application in Xiluodu Project is successful and shows that the traditional soil reinforcement technology is improved.
