1981年,在几次大暴雨的袭击中,四川省垮坝失事的水库共59座。59座水库中,有已成水库54座,在建水库5座。按工程规模分:有中型1座,小(一)型3座,小(二)型55座。从坝型看:有土坝55座,土石混合坝1座,石坝3座。由于洪水翻坝而导致失事的有48座,因渗透管涌等其它原因而引起失事的有11座。导致水库失事的原因是多方面的,而且往往是多种因素的组合。在诸因素中,降大暴雨是其客观因素,而工程本身在勘测设计、施工、管理等方面存在不少问题,以及对防汛保安工作重视不够,则是其主观原因。
In 1981, during several heavy rains, 59 reservoirs collapsed in Sichuan Province. Among 59 reservoirs, 54 reservoirs have been built and 5 reservoirs under construction. By project size: a medium-sized, small (a) type 3, small (b) 55. From the dam type: there are 55 earth mounds, earth and rock mixed dam 1, 3 dam. There were 48 crashes caused by the flood diversion and 11 crashes caused by other causes such as infiltration of pipes. The causes of the reservoir collapse are manifold and often a combination of several factors. Among the various factors, heavy rainfall is its objective factor, and the project itself has many problems in survey and design, construction and management, as well as insufficient attention to flood control and security work, which is its subjective reason.
