摘要
针对大厚度湿陷性黄土场地复杂环境下深基坑施工,为了尽可能地降低和减少施工事故及突发情况发生,基坑稳定性的过程监测就显得尤为重要。采用自动化智能监测系统,预警监控,主动防范基坑变形及支护结构失效,是实现基坑安全的有效措施。通过分析大厚度湿陷性黄土场地深基坑工程施工现状,提出基坑实时自动化监测的必要性,结合工程实例,对比研究提出自动化智能监测的优越性和可行性,为相关工程建筑深基坑施工及监测提供借鉴。
In view of the construction of deep foundation pits in large-thickness collapsible loess sites,sudden situations often occur under the complex environment.In order to reduce and decrease the risk of construction accidents and emergencies as much as possible,the process monitoring of foundation pit stability is particularly important.The use of automatic intelligent monitoring system can accomplish early warning monitoring and active prevention of foundation pit deformation and supporting structure failure are effective measures to achieve foundation pit safety.In this paper,we analyzed the current status of deep foundation pit construction in large-thickness collapsible loess sites,and proposes the necessity of real-time automatic monitoring of foundation pits.Combing with engineering examples study,we proposes the superiority and feasibility of automated intelligent monitoring to provide a reference for the construction and monitoring of deep foundation pits in related engineering buildings.
