本文的目的是介绍地震缺陷土坝（不包括尾矿坝）的工程修复方法，审查其优缺点，介绍这些方法的应用案例，并得出有关实践状况的结论。对已完成和正在进行的恢复项目进行了调查。这次调查确定了30座大坝的工程修复和22个操作修复。获得了36只母鼠的数据，并以表格形式列出。在这些大坝中，有13座基础存在抗震缺陷，15座基础存在缺陷，8座基础和堤防均存在缺陷。案例历史的概要介绍了约翰哈特大坝，萨迪斯大坝，摩门教岛辅助大坝，和欢乐谷大坝。
The purpose of this paper is to present methods available for engineered remediation of seismically deficient earth dams (not including tailings dams), to review their strengths and weaknesses, to present case histories of the application of these methods, and to draw conclusions about the state of practice. A survey of completed and active rehabilitation projects was made. This survey identified 30 dams with engineering fixes and 22 with operational fixes. Data was obtained and is presented in tabular form for 36 dams. Of these dams, 13 had seismically deficient foundations, 15 had deficient embankments, and 8 had deficiencies in both embankment and foundations. Synopses of case histories are presented for John Hart Dam, Sardis Dam, Mormon Island Auxiliary Dam, and Pleasant Valley Dam.
