摘要:
水电站大坝强震动响应特性是大坝震害快速评估和制定震后紧急处置措施的重要依据,也是大坝安全监测系统的重要部分,但是现有的大坝强震监测监测系统存在设备和维护成本高、自动化分析能力不强、参数速报不及时等缺陷。本文设计了一种新的大坝强震动监测系统:首先设计了一种15通道式强震动记录仪和一种防水型加速度计;然后针对常见的工频干扰和误触发问题,提出了一种实用的有效解决方法;最后设计了一套自动分析能力强、速报及时、管理便捷化的大坝强震动数据远程接收与在线分析软件。相比传统的分布式强震动监测系统,此新系统具有设备成本低、无人值守、强震动事件自动处理、误触发概率小、烈度等参数速报及时等特点,且通过短信、邮件实现了与智能手机的联动。此新系统已布设于大朝山、功果桥、乌东德等多个水电站,且最近多次强震事件验证了此系统的主要特点和可靠性。
Abstract:
Strong vibration response characteristics of dam in hydropower station is an important basis for rapid assessment of dam damage and formulation of emergency measures after earthquake, it is also an important part of dam safety monitoring system. However, the existing strong dam monitoring system has some defects,such as high equipment and maintenance costs、automation analysis ability is not strong、the parameter is not timely reporting and so on. A new monitoring system is designed in this paper:first of all, we designed a 15 channel strong motion recorder and a waterproof accelerometer. Then, a practical and effective solution is proposed for the common power frequency interference and error triggering. Finally, we design a set of remote data receiving and on-line analysis software,which can automatic analysis and report timely, it is easy to management too.Compared to the traditional distributed strong motion monitoring system,This new system has the advantages of low equipment cost, unattended, automatic processing of strong motion events,small probability of false triggering, the parameters such as intensity can be timely reported,and it can also achieve the interaction with smart phones through SMS, e-mail.This new system has been deployed in a plurality of hydro power station,such as Dachaoshan, Gongguoqiao, Wudongde etc. and recently several strong earthquake event have verified the main characteristics and reliability of the system.
