Abstract
This paper presents an investigation on the generation and distribution pattern of the temperature field within a vertical frozen soil wall by ADINA. The vertical freezing closure time was 7 days, and after a freezing time of 30 days, the vertical freezing formed a water-resistant frozen soil wall with a thickness greater than 1.6 m. The area within 1 m of the vertical frozen soil wall was affected due to the exchange of heat between the frozen and unfrozen zones. Thus, the spacing of vertical freezing pipes should be less than 1 m. For design of the freezing process, the effect of temperature at boundary zones should be taken into account. Marginal zones should be set aside because the effective/workable zone of freezing pipes is about 1 m. The width and depth of the vertical frozen wall should be larger than the designated sizes.
