东津水电站大坝渗流量异常测值分析

Analysis of Abnormal Seepage Flow Measurement Data in Dongjin Hydropower Station

大坝安全的正确判断是建立在可靠监测资料基础上的,因此需要对监测资料的合理性和可靠性进行检验。以东津水电站大坝为例,针对坝体及坝基渗流量原始观测成果中出现的明显异常数据,在成因分析的基础上,对明显不合理测值进行了处理,从而对坝体及坝基总渗流量实测性态做出了正确评价。

Correct judgment of the dam safety should be based on reliable monitoring data.Therefore,the reliability and rationality of the monitoring data should be carefully checked before these data are used to diagnose the safety status of a dam.In the original seepage flow observation results of the dam body and the foundation in Dongjin Hydropower Station,obviously abnormal data are found.Possible causes of these abnormal data are analyzed.Then,the obviously unreasonable measurement values are eliminated.Thus,the measured comprehensive seepage state of the dam body and the foundation could be evaluated correctly.
