Abstract
本发明公开一种增强锚固段稳定的吸能锚索装置及使用方法，涉及岩土工程锚固支护技术领域。包括锚索体、锚具、环形锁具、环形托盘、恒阻体、恒阻套筒、刚性套筒、弹性吸能弹簧、支撑体结构、内置摩擦增强环以及锁紧装置。锚具设置于刚性套筒内；锁具设置于刚性套筒后端外周；托盘设置于围岩表面与锁具之间。恒阻体套设于锚索体外周，恒阻套筒套设于恒阻体外周；弹性吸能弹簧设置于恒阻套筒与刚性套筒之间。内置摩擦增强环套设于锚固段外周；支撑体结构与锁紧装置连接。本发明通过弹性吸能—恒阻 / 摩擦耗能—界面主动增强的方式，吸收围岩变形释放的能量，降低锚索突发断裂风险，优化锚固段受力与结构配置，显著提升锚固段稳定性并抑制锚固失效。
