【摘要】 老化， 已在全国所有现存水利工程中有所体现， 而且有的很严重． 但由于其自身环境特点， 未能引起人们的重视， 从而导致一系列隐患和危害， 尤其作为水库枢纽建筑的溢洪道更易出现问题． 因此本文在国内外现有研究成果的基础上， 通过大量的现场调查和实测， 应用科学的方法对其老化程度进行单项和综合评价， 从定性与定量双重评价为出发点， 建立数学模型及评价标准， 以便给设计人员、管理人员提供决策参考．更多还原

【Abstract】 Aging is a common problem at present and some projects are very serious.But its diseaes has the characteristic of environment,thus it lead to a series of hidden trouble and endanger,especially spillway is regarded as pivotal project of water convervancy project that is appear problems constantly.On the basis of study result at home and abroad some appraises by investigation have been performed.A mathematical model and evaluation standards have been set to provide reference for the design personnel and management personnel.更多还原
