摘　　要：文中对某沿海城市大型基坑工程的施工技术、监测方案以及监测数据进行了分析。分析结果表明:在基坑开挖施工过程中围护结构变形规律与施工方案、周边环境有着密切的联系,有针对性地对基坑边坡土体和其支护结构及周边环境进行监测,对评价基坑施工方案设计合理性、施工安全性以及事故发生的预测性有着极其重要的作用;依据监测分析结果,可以有效地指导施工,避免经济损失。The construction technology,monitoring program and monitoring data of a large-scale foundtion pit of a coastal city are analyzed in this paper.The results show that the deformation rules of the enclosure structure are closely related to the construction scheme and the surrounding environment.Monitoring pertinently on slope soil of foundtion pit and its supporting structure and surrounding is of great importance for the evaluation of the rationality of foundation pit design,construction safety and accident prediction.The construction can be guided and the economic loss can be avoided according to the monitoring and analyzing results.
