GROUND FREEZING AND FROST HEAVE - A REVIEW

A review of methods of predicting frost depth and frost heave is presented. Initially, geothermal methods for predicting the extent of the frozen zone, and the temperatures in the freezing soil are reviewed. The majority of the review is devoted to mass transfer and heave in freezing soils. Methods of predicting frost effects including capillary, hydrodynamic and "discrete ice lens" approaches. Each approach is reviewed with particular emphasis on recent developments in the "discrete ice lens" models. The importance of the "Segregation Potential" method is discussed, and a synthesis of recent data is included. Problems and drawbacks with the use of these methods in engineering practice are reviewed. The paper continues to review the applications of these methods in solving practical engineering problems. Applications include the prediction of frost heave beneath buried chilled pipelines. The importance of soil stratigraphy and structure in controlling ice lensing processes is underlined, with pictures of the excavated frost bulbs from the Calgary frost heave test facility used to illustrate these effects. Future research requirements are reviewed, including frozen soil permeability, the effects of soil structure and stress history, and multi-dimensional effects on frost heave parameters.
