摘　　要：为了及时发现第四系巨厚含水松散层沉降变形,提出了一种在预设钻孔中埋入光纤B ragg光栅(FBG)传感器网络系统的监测方法。设计了松散层沉降变形的FBG实时监测系统,开发了一个储存监测数据的M icrosoftAccess数据库,采用MFC ODBC方法访问和操作该数据库,并利用TeeChart控件动态显示实时监测曲线和历史监测曲线。该系统的监测实验表明:设备运行正常,监测系统稳定,实现了监测数据的高效处理和准确预测。In order to detect the subsidence of Quaternary System extra thick hydrous unconsolidated strata in real time,a monitoring method with fiber Bragg grating （FBG）sensing network system embedded in the berehole is proposed. A FBG real-time monitoring system of stratum settlement deformation is designed, a Microsoft Access database used for saving monitoring data is developed. The MFC ODBC method is used in this system for accessing and operating the database,and the TeeChart control is used in this system for showing real-time monitoring curve and history monitoring curve dynamically. The engineering monitoring experiment shows that, the monitoring equipments run normaily, and the monitoring system runs stably,which achieves effectively treating and accurately predicting of the monitoring data.
