【摘要】 一般来说,大坝的几何学、物理力学、水利学、热力学、化学等综合特性都随着坝龄的增加逐渐变化,而这些变化有时最终会影响大坝健康安全运行。本文首先从大坝综合特性随坝龄的变化规律入手,解释了大坝老化的概念,提出了大坝老化研究的意义,叙述了大坝老化国内外研究的进展,并在此基础上强调了今后重点进行坝基老化系统研究的必要性。更多还原

【Abstract】 Generally, the geometrical, physical, mechanical, hydraulic, thermal, chemical and other properties of dams will deteriorate with the increasing of dam age and those deteriorations will affect the longevity and safety of dams. In this paper, firstly, the conception of dam ageing is clarified according to the age-related changes of dam properties. Secondly, some research trends on dam ageing are summarized. And finally, the necessity and importance of the systematic research on the ageing of dam foundation are emphasized.更多还原
