Abstract : This report presents the results of an investigation relative to the collection and improvement of techniques developed for the prediction of frost penetration depth and rate into non-uniform (multilayered) soil. The approximate techniques encompassing latent heat only, latent heat plus volmetric specific heat, and an adaptation of the modified Berggren equation are reviewed and compared. A sample problem is treated mathematically using each technique. Results indicate that an adaptation of the modified Berggren equation is the best technique for determining the depth of frost penetration in a non-uniform soil.
