摘要
主要介绍了近年来广泛应用于地铁震动环境中的扩孔型锚固新技术,扩孔型锚固技术相对于应用比较成熟普遍的膨胀螺栓锚固技术、化学粘结型螺栓锚固技术,有着其不可比拟的优势,基于此技术的优越性,本文着重阐述了地铁工程中扩孔型锚固技术的应用和实验监测情况,用事实和数据说话,通过和其他锚固技术做对比,介绍了扩孔型锚固技术的一些特点,进一步明确了在地铁工程震动和重负载状况下使用新型扩孔锚固技术的必要性,为今后类似工程施工提供了参考。
In this paper the new anchor technology which had been widely used in underground reaming vibration environment in recent years was described. The characteristic of reaming anchor technology was introduced. By comparing with other anchoring techniques, the necessity of new technology in the subway vibration and heavy loads circumstances was specified. Reaming anchor could be used for future similar projects.
