【Abstract】 The dam body of the Yaomenhe reservoir was poorly built.Its falling gradient of the back slope did not comply with the regulations and the permeation line is too high.So the stability of the dam remained as a serious problem.To solve the problem the permeating and flowing field of the dam body was calculated by means of the limited element program.The calculation showed the reasons for the over rising permeation line of the dam,conducted the stability analysis,and provided basis for safety argumentation of the dam body.更多还原
