摘要
通过研究某深基坑支护结构破坏前20天的坡顶水平位移、坡顶沉降位移、地下水位及深层水平位移历时曲线图等监测项目,从中可以看出,临界破坏时,位移监测值和地下水位监测值均发生了较大突变。这充分说明了信息化监测在深基坑开挖中的预警作用。最后指出自动监控系统是未来监测的发展方向。
Through studying the curves of the horizontal displacement of slope crest, the settlement displacement of slope crest, the subsoil water level and deep horizontal displacement of the monitoring project 20 days before the support structure of one deep foundation pit is destroyed, it can be seen a great mutation occured for the monitoring displacement and the subsoil water level at critical destruction. This fully proves the precaution function of the information monitoring in the accident of deep foundation pit. At last, this article points out that the automatic monitored control system is the direction of the future monitoring.
