摘　　要：为保证地铁深基坑施工安全,需要通过监测手段及时掌握周边地层、支护结构、管线、水位及建(构)筑物的动态,但在软土地层地铁深基坑面临的复杂高风险环境下,人工监测存在的滞后性可能会导致事故的发生。阐述了地铁基坑中智能化监测系统应用的实施过程及要点,监测结果表明:智能化监测技术在软土地层深基坑项目中可明显提升监测预警效率,通过智能化的监测手段及时反馈开挖过程中基坑的状态及其对周边环境的影响,可很大程度上弥补人工监测“滞后反应”的缺陷,可有效预防工程破坏事故和环境事故的发生,在软土地层地铁深基坑中值得推广使用。对智能化监测系统后续的发展方向提出建议。In order to ensure the safety of the deep foundation pit construction of metro,it is necessary to timely master the dynamics of the surrounding strata,supporting structures,pipelines,water level and buildings( structures) through monitoring means. However,the lag of manual monitoring may leadto accidents in the complex and high-risk environment faced by the deep foundation pit of metro in soft soil stratum. The implementation process and key points of the application of the intelligent monitoring system in the foundation pit of metro are elaborated. The monitoring results show that: the intelligent monitoring technology can significantly improve the monitoring and early warning efficiency of the deep foundation pit project in the soft soil stratum. The status of the foundation pit during the excavation process and its impact on the surrounding environment can be timely fed back through intelligent monitoring means,which can make up for the defect of " lagged response" of manual monitoring to a great extent. It can effectively prevent the occurrence of engineering damage accidents and environmental accidents,and it is worthy to be extensively used in the deep foundation pit of metro in soft soil stratum. The suggestions on the subsequent development direction of the intelligent monitoring system are put forward.
