【正文】 embankment), the seepage volume, and its criticality. Embankment slope stability is usually improved by ?attening the slopes or providing a toe berm. This slope stabilization is usually bined with drainage measures at the downstream toe. If the stability of the upstream slope under rapid drawdown conditions is of concern, then further analysis and/or monitoring of resulting pore pressures or modi?cations of reservoir operations may eliminate or reduce these concerns. Finally, raising an earth ?ll dam is usually a relatively straightforward ?ll placement operation, especially if the extent of the raising is relatively small. The interface between the old and new ?lls must be given close attention both in design and construction to ensure the continuity of the impervious element and associated filters. Relatively new materials, such as the impervious geomembranes and reinforced earth, have been used with success in raising embankment dams. Rehabilitation of an embankment dam, however, is rarely achieved by a single measure. Usually a bination of measures, such as the installation of a cutoff plus a pressure relief system, is used. In rehabilitation work, the effectiveness of the repairs is difficult to predict。 they serve as guidelines, reminders, and examples of what to look for and report on, but they serve as no substitute for an experienced, interested, and observant engineering eye. Several key factors should be examined by the engineer in the context of the mandate agreed upon with the dam owner, and these together with relevant and appropriate putations of static and dynamic stability form the basis of the assessment. It is only sensible for an engineer to mit to the evaluation of the condition of, or the assessment of, an existing and operating dam if he/she is familiar and fortable with the design and construction of such things and furthermore has demonstrated his/her understanding and experience. Rehabilitation Measures The main factors affecting the performance of an embankment dam are (1)seepage。 Assessment. Introduction Many major facilities, hydraulic or otherwise, have bee very old and badly deteriorated。 中文 2575 字 附錄一 外文翻譯 英文原文 Assessment and Rehabilitation of Embankment Dams Nasim Uddin, ., Abstract: A series of observations, studies, and analyses to be made in the field and in the office are presented to gain a proper understanding of how an embankment dam fits into its geologic setting and how it interacts with the presence of the reservoir it impounds. It is intended to provide an introduction to the engineering challenges of assessment and rehabilitation of embankments, with particular reference to a Croton Dam embankment.
