美国陆军工程师团对美国527座正在运行的大坝进行安全检查和维护,其中有的坝已有145年的历史。各种仪器在评价大坝能否继续安全运行中起着重大作用。一般情况下监测仪器由丁作人员每月测续一次。在水库最初蓄水期间和高水位时,监测周期则缩短为每日一次,并将测值交设计工程师进行解释、评价和分析。另外,大坝运行状态由当地正式检查团与现场责任办公室组成的综合检查团进行定期检查,根据坝的年限和运行史,1—5年检查一次。准确地预计一项水电工程需用多少仪器,用什
The U.S. Army Corps of Engineers conducted safety inspections and maintenance of 527 running dams in the United States, some of which have a history of 145 years. Various instruments play a significant role in assessing whether a dam can continue its safe operation. Under normal circumstances, the monitoring equipment by the staff of Ding once a month. During the initial storage period and high water level of the reservoir, the monitoring period is shortened to once a day, and the measured values are submitted to the design engineer for interpretation, evaluation and analysis. In addition, the dam operation status is checked regularly by the comprehensive inspection team composed of the formal inspection team and the on-site responsibility office of the local dam, and the inspection will be conducted in 1-5 years according to the life span and operational history of the dam. Accurately predict how much equipment and what to use for a hydropower project
