Learning methods and activities

Two online learning modules are mandatory as course preparation and need to be achieved during the month of September to allow more time on practical field aspects of frozen ground science and engineering during the intensive course. These online modules will focus on heat transfer and freezing-thawing soil mechanics.

MODULE 1: HEAT TRANSFER (2-13 SEPTEMBER 2019, 9 hours of lecture and 9 hours of personal work)

The module introduce the students to the basics of heat transfer in freezing soils. Conduction, convection and radiation heat transfer mechanisms as well as phase change and enthalpy are covered. Thermo-physical properties of soils and construction materials are presented including various prediction models available from the literature. Effects of insulation layers in road structures are also discussed in terms of frost protection and risk of differential surface icing.

MODULE 2: FREEZING-THAWING SOIL MECHANICS (16-27 SEPTEMBER 2019, 9 hours of lecture and 9 hours of personal work)

This module introduce the students to the mechanics of freezing, frozen and thawing soils. It includes basic information on freezing soils: the mechanics of frost heave and the strength, stiffness and deformation characteristics of frozen soils. The module discuss the movement of water in freezing and frozen soils, with attention given to the unfrozen water content in fine-grained soils (silts and clays) at temperatures below 0 °C and the resulting hydraulic conductivity of these materials. This module also presents the thaw consolidation theory and the settlement behavior of ice-rich soils as frozen ground thaws.

10 places are available for professionals. Places will be awarded to the first registered participants.
