Intro Foundations In Areas of Significant Frost Penetration, 2 PDH

Jun 3, 2013 - Areas of significant frost penetration may be defined as those in which freezing temperatures occur in the ground to sufficient depth to be a significant factor in foundation design.

Course Outline


Learning Objectives

Upon completion of this course you will:

• Learn about the characteristics of seasonal frost and permafrost and how they affect the foundations of buildings and other infrastructure;
• Learn the geographical regions of North American where significant frost penetration is an issue in design of foundations;
• Learn how the more intense the winter cooling of the frozen layer in the annual frost zone and the more rapid the rate of frost heave, affects the intensity of uplift forces in piles and foundation walls;
• Learn about the engineering problems that may arise in areas of significant frost penetration such as the difficulty of excavating and handling ground when it is frozen; soft and wet ground conditions during thaw periods; surface and subsurface drainage problems; special behavior and handling requirements for natural and manufactured materials at low temperatures and under freeze-thaw action; possible ice uplift and thrust action on foundations; condensation on cold floors; adverse conditions of weather, cost, and sometimes accessibility; in the more remote locations, limited local availability of materials, support facilities, and labor; and reduced labor efficiency at low temperatures;
• Learn about progressive freezing and frost heave of foundations that may develop under refrigerated warehouses and other similar facilities;
• Learn about the most important factors contributing to the existence of adverse foundation conditions in seasonal frost and permafrost regions; and
• Learn how freezing and thawing indexes are employed in foundation design.
