摘　　要：分布式传感技术,在提供关于结构某种时空连续信息的同时,亦产生海量数据需存储和处理。出于工程自动化实时监测的需要,构建基于布里渊散射的大坝混凝土裂缝分布式光纤远程监测系统。系统构建的主要工作,是编制位于监控中心的高性能计算机上运行的监测软件,用于系统检测控制、监测数据即时存储、分析处理、查询显示及预警等功能。通过监测系统在某大坝工程混凝土裂缝监测中的应用,显示监测软件各种功能的特点,并表明软件系统的可靠性,可在工程中推广应用。Out of the need for automatic and real-time monitoring of engineering cracks, a distributed fiber optic concrete crack remote monitoring system for large dams based on Back Brillouin Scattering is constructed. The major work of con-structing a monitoring system is developing the monitoring software that works in high performance computers situated in a monitoring center. This system can provide system detection control, instant monitoring data analysis and processing,monitoring result search and display, as well as early warnings. According to the application of the system to the concrete crack monitoring in a large dam, the various function features of the system are tested. This software is reliable and is worthy of further application in practical engineering.
