From curtailed budget, it is required to reduce allocation of additional wage based on forensic treaty, in order to establish countermeasure for frost heave from road management or slope stability efficacy.In this paper, the authors analyzed meteorological observation data Aomori, Nagano and Hokkaido including assimilated our data from Chino City Nagano, as to statistical period proximately two or three generation considering with deterioration of civil facilities. At first, we categorized each meteorological element on Dec., Jan., Feb. and Mar. adjust data of descriptive statistic for finding analogous characteristic results between Honshu and Hokkaido concern with cryogenic circumstances. Secondly, our research member scrutinized frozen ground with field survey, geo —morphological features and temperature focused on Nagano Pref. Finally, occurrence of frost heave and statistical analyzed climatic and hydrologic data, we concluded that several areas in Honshu Japan should be amended Hokkaidos maintenance of social infrastructure in order to alter or promote safety community swiftly.
