Field Monitoring of Volcanic Slope Subjected to Freezing and Thawing and Its Evaluation
Rainfall-induced failures of natural and artificial slopes such as cut slopes, which are subjected to freezing and thawing, have been frequently reported in Hokkaido, Japan. In particular, many failures occur intensively from spring to summer seasons. This study aims at clarifying failure mechanisms and soil behavior of in-situ slope subjected to rainfall and freeze-thaw process. Firstly, a series of model test was performed on volcanic slopes in order to grasp failure conditions. Secondly, the changes in soil moisture, deformations and temperatures in the slope were mainly investigated using various monitoring instruments such as soil moisture meters for the in-situ slope. On the basis of those data, a prediction method for slope failure was discussed in detail.
