Soil freezing cannot be avoided in eastern Hokkaido where it is cold and the snow is not very deep in the winter. In such a region, soil freezing inflicts great damage to theagricultural facilities. Especially, the crumbling of slopes and destruction of lining on the channels used for irrigation and drainage are caused by the soil freezing. The purpose of this experiment is to select a suitable method of lining and the proper thickness of backfill for the channel in a soil freezing region. The conclusion obtained is that the force of a frost heave on a concrete lined channel is decreased to between 1/8 and 1/10 of that in earth channels. When there is a backfill for the concrete channel, the force is reduced to between. 70% and to 80% of that in a cocrete chnnel without backfill.
