Two Cases: The New Danger Resulted from the Earth Dam Reinforcement

There were about 40% dangerous among the 86 000 reservoirs have been built in China. The large range reinforcement to the dangerous reservoir have been implemented in nation for three times from 70s. The main minitype reservoirs would be fulfilled reinforce-ment in 3 years from 2007 and the others maybe need to 10 years. Almost all of the danger-ous dams are earth dams. The new danger resulted from the earth dam reinforcement because the geological exploration is insufficiency, understanding the dam parameters and the interior disfigurement are deficiency, and the construction is impertinence to the real condition. Two analysis case were given in this paper. The reason and mechanism have been studied about the deep slip in the dam heel of Pubu Reservoir in Nanxiong, Guangdong Province. The cranny occurred and evolution in the dam crest of Caoling Reservoir in Yongzhou, Hunan Provimce, have been explained by FEM simulation based on the ESDA programme. The con-clusion is significant in the dam reinforcement practice and reference to the alike engineering.
