摘要：

本文介绍了北京北苑车站钻孔灌注桩施工中断桩事故的处理及施工方法，成功解决了该工程的B21-1桩深孔位断桩事故，处理结果良好，经法定检测部门检测达到了设计技术规范要求。该方法简单易行，对类似工程问题，具有指导作用。

关键词: 干挖孔；深孔断桩；钻孔灌注桩

Abstract:

This paper, based on a case study on how to deal with a pile-broken accident during concrete-filling hole construction at Beiyuan Metro Station, introduces a workable approach to the pile-broken accident at B21-1 Hole, achieves an planned technological standard which was examined by an authorized unit. This approach, easy but applicable, can provide a reference for similar accidents.

Key words:

dry-excavation hole; broken pile in deep hole; concrete-filling pile
