Abstract
Hachinohe area which is located in the north east has a climate of low temperature and less rainfall during the winter period. On the other hand, in the Hachinohe area, volcanic cohesive soil was depositing widely and thick called the Takadate loam. That is region specific soil and sensitive soil on the frost heaving action. There are many cases that are not construction aggressive frost heave measures method in Cut slope, In recent years these problems often occur and has become a regional problem of maintains. In this study, we examined the seven countermeasures method, which was carried out in situ test. And from test recording to calculate the thermal conductivity of the soil, and induces the thickness of the heat insulating layer by analysis to verify the integrity of in-situ test results. As a result, As a result, we were able to confirm the method of calculating the insulation thickness and the possibility of measures method that does not use a heat-insulating material.
