美国许多建于２０ 世纪初的大坝在设计时没有考虑发生地震的情况， 目前正通过运用预测的最大可信地震对大坝进行常规分析。建议建立一个全国性大坝地震和稳定性分析数据库， 这将使本行业决策过程更有依据。 Many of the dams in the United States built in the early 1900s were not designed to consider earthquakes and are currently being routinely analyzed by using the largest credible earthquake forecast. It is suggested that a nationwide dam seismic and stability analysis database be established that will provide more evidence for the industry’s decision-making process.
