When frost heave occurs, the ground is lifted to the same direction of heat flow, while during thawing, the force of gravity acts downward. This means that the direction of lifting due to frost heave and the direction of gravitational force acting during subsidence are different on a slope. Consequently, the ground moved by frost heave does not return to its original position, instead it is moved to a position further down the slope. This movement due to the repeated freeze-thaw process is believed to trigger the collapse of the slope.<br>In the present study, four experimental plots planted with different types of vegetation were set up on the slope of an embankment within the campus of the Kitami Institute of Technology and the behavior of these slopes during the freeze-thaw process was observed over five seasons. The following results were obtained; (1) the behavior characteristics of the surface of the slopes in the freeze-thaw process of seasonally frozen ground were measured; (2) it was shown that movement down the slope, which is believed to trigger collapse by slipping, occurred during the thaw period and that the amount of movement depended on the extent of the frost heave, the vegetation cultivation conditions and the presence of reinforcing vegetation.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"42709","nameIdentifierScheme":"WEKO"}],"names":[{"name":"UENO,
