摘要
强震监测是大坝安全监测的重要内容之一,强震监测成果对大坝的安全性和稳定性分析有重要作用。本文根据水电站枢纽工程实际对深溪沟水库大坝强震监测系统设计开展研究,并对仪器的性能指标和数据采集处理分析软件进行了全面阐述。通过深溪沟水电站建设大坝强震监测系统的运行实践,大坝强震监测系统可以在地震发生后短时间内自动获取强震动加速度记录,储存地震波数据,并显示大坝坝体各测点的地震反应过程。强震监测结果进一步验证了设计烈度,为判定震后大坝安全性提供了支持。
The monitoring of the earthquake around the dam is the key content of dam safety and the seismic monitoring result plays an important function in the analysis of the safety and stability of the dam. This paper studies and designs the seismic monitoring system of Shenxigou Hydropower Station according to actual situation of the hydropower engineering. The paper also discusses the performance of the instrument and the software about the acquisition and analysis of the seismic data. Through the operation of the seismic monitoring system of Shenxigou Hydropower Station, the system can get the strong earthquake motion acceleration records, store the seismic data, and display the reaction process of the earthquake in each point of dam body. The monitoring result of the strong earthquake motion meets the designed seismic intensity, and it is support to analyze the safety and reliability of the dam building after the earthquake.
