摘　　要：在城市土地资源有限的情况下,把三维空间利用率的提高成为人们的共识。因此深基坑越来越多。为了保障深基坑开挖施工期间周围建构筑物及施工人员的安全,因此基坑监测变得越来越重要。在基坑监测过程中,基坑外部水位变化是整个基坑监测过程中非常重要的内容;坑外水位的变化和止水帷幕的止水效果息息相关的,而止水帷幕质量的好坏,对基坑开挖过程中的安全性起到很大作用。作者针对深基坑开挖施工中出现的坑外水位变化现象做了阐述,作者首先介绍了坑外水位变化的原因;其次针对坑外水位变化所使用的监测方法;最后,作者通过一个实际的工程案例验证了深基坑开挖后出现的坑外水位变化现象。In the context of limited urban land resources,improving the utilization rate of three-dimensional space has become a consensus among people.Therefore,there are more and more deep excavations.In order to ensure the safety of surrounding buildings and construction personnel during the excavation of deep foundation pits,foundation pit monitoring has become increasingly important.In the process of foundation pit monitoring,the change of external water level is a very important content throughout the entire foundation pit monitoring process;The change of water level outside the pit is closely related to the waterproof effect of the waterproof curtain,and the quality of the waterproof curtain plays a significant role in the safety of the excavation process of the foundation pit.The author elaborates on the phenomenon of changes in water level outside the excavation of deep foundation pits.The author first introduces the reasons for the changes in water level outside the pit;Secondly,the monitoring methods used for changes in water level outside the pit;Finally,the author verified the phenomenon of water level changes outside the deep foundation pit after excavation through an actual engineering case.
