• Abstract:
  The BERG2 microcomputer program uses a methology similar to the Modified Berggren method (Aldrich and Paynter, 1953) to estimate the freeze and thaw depths in layered soil systems. The program also provides an estimate of the thaw consolidation in ice rich soils. BERG2 differs from the original Modified Berggren method since it uses the actual frozen and unfrozen material thermal properties instead of average values. This approach improves the accuracy of predictions. ; BERG2 provides an improved user interface over the original BERG program, (Braley 1984). It also requires less input as a result of the ability to compute many of climate parameters from the more common data. As a result the user required input is significantly reduced. ; This manual provides the user information concerning the use of BERG2, its strengths and its limitations. It also provides a discussion of the equations used in development of the program for those who wish a better understanding of the analysis process.
