摘要
目前各地的主要规范、工程标准规定确定的预警值一般都是根据不同等级,采用统一的控制指标,这在实际工程的应用较为困难,而且经济性差。本文运用统计分析的方法,通过对东南沿海某地区部分基坑工程的监测数据分析,从围护结构水平变形方面对监测警戒值的设定提出了一些建议,可为以后的工程安全监测提供参考,从而既保证工程安全、变形控制达到要求,又有效减少不必要的报警次数。
At present, the alarm value in different areas is determined by the main specification and engineering standard provisions, which adopts the extremely strict unified control standards, but it is difficult and uneconomical for the project construction. In this paper, through statistical analysis of monitoring data obtained from the construction process of foundation pit engineering in the southeast coastal area, some suggestions are proposed the aspects of retaining structure horizontal deformation on monitoring alarm value set. The results would provide reference for future engineering safety monito- ring. Based on the safety of projects, it reduced successfully many unnecessary alarm events.
