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广泛.自进式锚杆是一种新型锚杆,集钻孔、锚杆安装、注浆、锚固为一体,主要用于断层破碎带岩体的支护。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托,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,将岩石锚固技术融入复杂地质情况下的土体加固施工,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的综合运用上进行了初步探索,取得了一定的技术成果。
Soil anchor is widely used in deep foundation supporting and retaining,slope reinforcement,landslide remediation,pools’anti-floating,anchored retaining wall and structures’anti-overturning etc in our country.Self-boring anchor is a new-type anchor,which has the functions of drilling,installation,grouting and anchoring simultaneously.It is mainly used to support the rock in fault fracture zone.According to the upper overburden layer excavation of left and right bank outlet shaft in Xiluodu hydropower station,by proving and practicing the soils’anchor technology under different geological conditions,rock anchor technology is integrated into soil reinforcement construction under complex geological conditions.This technology changes the traditional soil reinforcement technology.Primary exploring is done about the choice of drilling machines,drilling technology research and applications of related reinforcement technology,at last technical achievements are obtained.
