Abstract
In recent years, the usefulness of soil nailing method is reported as earthquake resistance measures of existing embankment. Past studies on the use of small diameter reinforcement materials as soil nailing method in snowy cold environment are proceeding. However, from the new evaluation results of the probability of earthquake occurrence, there is a possibility that the momentum of seismic reinforcement in soil structure in snowy cold environment also increases. In this study, we are conducting observation of the dynamics in cold environments by constructing soil nailing method using large diameter reinforcing material (i.e. dowelling) on test embankment, and conducting test construction of surface work using geogrid. From the results of the pull-out test, it was confirmed that although the resistance to withdrawal had decreased after freeze-thawing, there was no influence on the current design.
