It's also the largest dam removal in the history of a country with 80,000 of the man-made structures, many of them aging, silting up, and no longer useful (or at least necessary).

这也是美国历史以来最大规模的大坝拆除项目，将拆除80,000个人造构件，其中大多数已经老化，淤塞，无用(至少是不必要了)。

Structures are always subjected to various adverse factors during its long-time service, such as fatigue, environmental corrosion, material aging, etc.

在结构长期服役期间，疲劳、环境腐蚀和材料老化等因素的作用会引起结构损伤的累积。

Beyond prices, we also see failures during peak periods in many places due to aging infrastructure and fragile grid structures (as evidenced by unanticipated brownouts, blackouts, and rolling brownouts in some regions).
