【摘要】 本文针对功果桥水电站的现场实际情况,就强震观测系统在功果桥水电站中的应用,从强震监测台阵布设的技术和方法做了详细阐述,包括强震系统的设计、强震台阵的构成、仪器的性能指标以及数据采集分析等。通过分析可知,功果桥水电站强震观测系统可以在强震发生后短时间内获取强震动加速度记录,迅速记录地震波,从而得出坝体不同部位的地震反应过程。借此强震动记录,可以研究大坝结构对地震动的影响、确定地震动衰减规律,为震后判定大坝建筑物的安全性和修复提供基础性技术数据。同时,可以积累丰富的大坝强震数据,为同类大坝的抗震设计和相关地震工程发展积累基础资料。更多还原

【Abstract】 In this paper,the applicat ion of strong earthquake monitoring system on the Gongguoqiao hydro dam are introduced in detail along with the actual situation o f the Gongguoqiao hydro dam,Including strong system design,the earthquake performance of the array structure,instrument and data collection and analysis,etc.,through the analysis of earthquake known work fruit bridge hydropower station system can be obtained in a short period of time after the earthquake occurred strong motion acceleration records,records quickly,calculated the dam seismic response from different parts of the process.To dam structure of earthquake strong motion records can be research,identify the influence of ground motion attenuation laws,to determine the safety of the dam building after an earthquake and repair provide basic technical data.At the same time,have accumulated rich the dam earthquake data,for the seismic design of similar DAMS and to accumulate basic data related to earthquake engineering development.更多还原
