Frost-protected shallow foundation: work in seasonally-freezing grounds, practice of thermal calculation

Grounds and foundations, underground structures

The object of research is frost-protected shallow foundations.

The article focuses on a technique of solving the nonstationary and nonlinear problem of freezing/thawing of soil in a 2D target setting, using software based on the finite-element method. The COSMOS/M package from Structural Research & Analysis Corp. is used as an example.

The article also mentions some peculiarities of data input, caused by the non-linearity and nonstationarity of the problem.
