In regions of dense permaforst ice layers are generally found in continual and periodically acting currents of water, as well as in hollows inundated by soil and subterranean waters. In order to analyze ice processes, and determine antifreeze measures, it is expedient to divide ice passages into the following groups: (a) ice layers of surface waters (river and spring); (b) ice layers of subterranean waters; (c) ice layers of soil waters (below-freezing); (d) ice layers of mixed waters. The conclusions are drawn as follows: (1) For dense permafrost regions the passage of small water current and springs in constructions with no ice layer formation, and aided by open and heated troughs, or only by means of concentrating the water current, can not be recommended in view of large heat losses; (2) Drains are very effective anti-ice means when applied in channels and for intercepting subterranean and soil waters in hollows. During the process of designing the drainages, measures must be envisaged which prevent the freezing of water in them, in collection and transportation; (3) A retention of the ice layer above the artificial constructions should be recommended in order to control spring and mixed ice layers in valleys with insignificant gradients; (4) Frost-waterproof belts consisting of vertical and horizontal waterproof shields can be applied to control ice layers fed by sub-freezing waters; (5) Planning the soil roadbed of small bridges and culverts in dense permafrost regions can be done in a unified complex with antifreeze constructions.
