| Compared with the other dams, earth-rock dam is dominant and the most commonly used. Due to the low economic level dam construction technology immaturity and other reasons, there are many dam projects of poor quality, dangerous hazards, and more serious problems such as poor project management. Dam seepage deformation is the main disease. Therefore, research in the field of dam on the dam seepage is of significance.In this paper, based on the reservoir project in Henan province, using the numerical method, the dam seepage safety characteristics are studied.The research content of this paper mainly includes:(1) Details of the dam's development at home and abroad, the basic method for solving seepage; the basic concepts of seepage, seepage differential equations and definite conditions;(2) Based on finite element and seepage theory, using software to calculate the various critical sections'seepage field of Wuyue earth-rock dam in the characteristic reservoir water level in Henan province. Analyzes the results;(3) Using the theory of seepage deformation, analyzes the seepage deformation of main dam, calculate the critical seepage gradient;(4) Based on the fuzzy mathematics theory, using multi-level fuzzy comprehensive evaluation, researches the methods of the dam security evaluation. |
