基坑工程桩锚支护体系锚杆内力监测浅析

Elementary Discussion on Internal Force Monitoring of Pile-anchor Retaining System in Foundation Pit Engineering

讨论了实际基坑监测过程中遇到的一种锚杆内力变化状态,案例中锚杆内力变化与规范监测报警值描述的情况存在差异,笔者分析了内力变化的具体原因,指出该情况下锚杆内力变化对基坑工程安全性的影响。结合相关标准规范,对该案例的锚杆内力监测报警进行了探讨,以期为锚杆内力的监测报警提供参考。

This paper mainly discussed about an actual encountered state of anchor internal force change in the process of foundation pit monitoring. There were some differences between the anchor internal force change in the case and situation and the described standards. The author analyzed the specific reasons about the change of the internal force and pointed out that anchor internal force change would have influence on the safety of foundation pit engineering in this kind of case. Combined with the related standards, the internal force of anchor bolt monitoring and giving an alarm was discussed to provide references for monitoring and giving an alarm of the anchor internal force in this paper.
