The characteristics of frost heave have been evaluated with experimental results based on individual testing apparatus and methods even though frost heave testing methods have already been standardized in Japan and the U.S., such as through JGS 0172

A series of 1-D freezing experiments were conducted to simulate frost heave in saturated coarse-grained soil (CGS) with variable fines content. Visible frost heave occurred in CGS that contained a considerable fraction of fines when supplied by an ex

The freezing method for underground construction has been attracting attention owing to its non-polluting characteristics. This method requires precise forecasting of freezing behavior and countermeasure technology against frost expansion. To improve

Frost heave is a well-known phenomenon in cold regions. It may happen in the wet clayey ground during winter in seasonally frozen regions and during autumn to winter in active layers in permafrost regions. The railway track upheaval, which happens in

Most of the presently available practical frost heave prediction methods were derived from and for one-dimensional (1D) situations. However, the real desire of engineers is a multi-dimensional frost heave analysis. It is convenient to simply accumula
