Technical framework for dam safety monitoring system evaluation
-
摘要: 在梳理国内外大坝安全监测相关规范及实践经验基础上，研究提出大坝安全监测系统评价总体框架安全监测设施可靠性及完备性、监测系统运行维护和自动化系统评价要素及评价方法等。大坝安全监测系统评价内容包括监测设施完备性评价、监测设施运行维护评价和自动化系统评价。监测设施完备性评价基于监测设施考证资料、现场检查与测试以及历史测值分析等方法，评价为可靠或基本可靠的监测设施是否满足大坝安全监控要求；监测设施运行维护评价包括运行管理保障、观测与维护以及资料整编分析等；监测自动化系统评价内容包括数据采集装置、计算机及通信设施、信息采集与管理软件、运行条件和运行维护等方面。监测系统综合评价分为正常、基本正常和不正常3个等级。评价为正常，应继续运行；评价为基本正常，可继续运行，但应及时修复完善；评价为不正常，需及时更新改造。Abstract: On the basis of reviewing the relevant technical specifications and practical experiences on dam safety monitoring at home and abroad, the overall evaluation framework of dam safety monitoring system is put forward in this paper. The evaluation elements and methods of the reliability and completeness of the dam safety monitoring facilities, the operation and maintenance of the monitoring system and the automation system are carried out. The evaluation of the dam safety monitoring system includes the evaluation of the completeness of the safety monitoring facilities, the evaluation of the operation and maintenance of the monitoring facilities and the evaluation of the automation system. Based on the verification data of the monitoring facilities, on-site detection and testing, and historical measurement analysis, the monitoring facilities are evaluated whether it is meet the requirements of the dam safety monitoring. The evaluation of operation and maintenance of the monitoring facilities includes operation management guarantee condition, observation and maintenance, data compilation and analysis, etc. The evaluation content of the monitoring automation system includes data acquisition device, computor and communication equipment, information acquisition and management software, operation conditions and operation maintenance, etc. The comprehensive evaluation of the monitoring system can be divided into three levels: normal, basically normal and abnormal. If the evaluation of the monitoring system is normal, it should continue to operate; if the monitoring system is evaluated as basically normal, it can continue to operate, but it should be repaired and perfected in time; if the evaluation of the monitoring system is abnormal, it needs to be updated and reformed in time.
