摘　　要：龙江水电站枢纽工程大坝安全监测系统涵盖大坝主体结构、地基基础、两岸边坡等相关重要部位。大坝预警系统根据数理统计法、历史监测资料及相关规范设定预警指标,对异常测值进行比对分析,通过预警系统平台进行现地及远程报警,能够及时提醒管理人员关注,针对突发情况及时采取应对措施,实施应急预案。实践表明,预警系统大大降低对监测数据进行初步处理分析的烦琐重复劳动,极大地提高监测数据管理与分析的效率和水平,达到预警减灾的预期效果,为今后推广应用积累丰富的经验。Longjiang hydraulic project dam monitoring system covers the important parts of the dam main structure, the foundation and two sides slope monitoring. Dam early warning system sets warning indexes based on mathematical statistics method, historical monitoring data and related specifications. It can compare and analyze abnormal values send, situ and remote alarm to timely remind managers and operators to concern about, and carry out contingency plans of emergency situations. Practice shows the system greatly reduces the tedious labor of monitoring data preliminary process and analysis, greatly promotes the efficiency and level of monitoring data management, and achieves the desired effect of early warning and disaster reduction, also accumulates rich experiences.
