The action of ice layers on the condition and operation of artificial constructions can appear in the following aspects: (a) surface coverage of bridges and culverts by ice obstruction of filtering dams leading to a lowering of the water permeable capability of constructions in the spring, as well as the danger of ice escape onto the road and the interruption of traffic; (b) force and mechanical action on the elements of construction in the form of horizontal pressure of the ice during its thermal expansion, vertical pressure (heaving) arising during the development of the hydrostatic pressure of the ice water, and the destruction of elements during dam ruptures; (c) heat-insulating action on the foundations of constructions in the form of melting or cooling effects leading to the development of general deformations of bridge foundations. The indicated aspects of ice actions to some degree affect the longevity and the reliability of water-permeable constructions and, naturally, must be calculated in the form of special engineering computations and requirements.
