  • Verifying the Effect of Anti-Frost Heaving Measure for Cut Slope of the One-Pack Heat Insulator Gabion by Test Construction and Heat Transfer Analysis

抄録

<p>In cold and snowy regions such as Hokkaido, there are many examples of conventional anti-frost heaving measures on the cut slope by laying special gabion boxes to cover the slope surface, and this has become a common practice against frost heaving. However, do not prevent freeze penetration due to cold weather into the ground on the mountainside and it causes wavy deformation of special gabion boxes. Conventional special gabion boxes also require manual labor on slopes and at high elevations, complicating maintenance/management and causing lower workability and safety after the special gabion boxes have been installed. Therefore, we have researched and developed one-pack heat insulator gabions as a new anti-frost heaving measure on the cut slopes. In this study, countermeasures were test installed in winter and fall. The results of the test construction clarified that frost heaving may occur in case construction is performed in winter due to freezing penetration into the backside ground, even when a countermeasure against frost heaving is being taken. It was also confirmed that avoiding winter construction would fully demonstrate the effectiveness of the one-pack heat insulator gabions as a countermeasure.</p>
