【 摘 要 】

Freezing and thawing damage is one of the major problems of the Fengman concrete dam. Based on the temperature records of the dam, appropriate heat transfer boundary conditions in the dam body are suggested. A three-dimensional finite element model is used to determine annual variation of temperature field of the dam as a case study. The deterioration problem of concrete dam owing to freezing and thawing effect is investigated.
