Abstract: Aiming at the problems such as low work efficiency, weak professional level, and poor timeliness existing in the manual analysis, information technology is adopted and a set of dam safety monitoring data diagnosis and analysis system is designed and developed, which has obvious advantages in monitoring data preprocessing, distribution map drawing, engineering analogy, abnormous situation feedback, and et al. As well, it can realize the automatic generation of monthly reports, quarterly reports, annual reports, earthquake express reports and comprehensive monitoring data analysis reports. The application shows that the system can significantly improve the efficiency and quality of dam safety monitoring data diagnosis and analysis work, and it is worthy of promotion in dam safety management industry.

Key words: dam, monitoring data, diagnosis and analysis, function design

摘要： 针对现有人工分析手段存在的工作效率低、专业水平弱、时效性差等问题，利用信息化手段，设计研发了一套大坝安全监测信息诊断分析系统，在监测数据预处理、分布图绘制、工程类比、异常情况反馈等方面具有明显优势，能够实现监测月报、季报、年报、地震快报及监测资料综合分析报告的自动生成。工程应用表明，该系统能够显著提高大坝安全监测信息诊断分析的工作效率和质量，值得在大坝安全管理行业内推广应用。
