湖南省建国以来,兴建了各类水库12725座,约占全国水库总数的1/7,其中大中型水库249座,土石坝工程占85.1％。据不完全统计,湖南省仅中型水库就有15处坝体发生过滑坡。近来在续建配套的40多座中型水库设计复查工作中发现,约有25％的大坝未作过稳定分析,坝体安全有问题,或通过验算存在不同程度的隐患,需要加固处理。可见,对土石坝工程进行加固除险设计工作,具有普遍意义。对这些已建并已运行多年的工程,坝体填
Since the founding of the People’s Republic of China, a total of 12,725 reservoirs have been built, accounting for about 1/7 of the total number of reservoirs in the country, including 249 medium and large-sized reservoirs and earth-rock dam projects accounting for 85.1%. According to incomplete statistics, only 15 medium-sized reservoirs in Hunan Province have landslides. Recently, in the review and design of more than 40 medium-sized reservoirs, it has been found that about 25% of the dams have not undergone a stable analysis and there are problems with the dam safety or have hidden dangers in varying degrees through checking and require reinforcement. Can be seen on the embankment dam reinforcement project design work, has a universal significance. For these projects that have been built and have been in operation for many years, dam bodies will be filled
