Abstract

<p>In this study, we examined a research method to evaluate the effect of freeze-thaw history on the erosion control effect of vegetation work. We have prepared specimens in which Poa pratensis L. was grown, given the freeze-thaw history, and then conducted erosion tests. The erosion test apparatus and erosion test method developed in previous study were adopted for the research methodology. In addition, the freeze-thaw history was given by placing cooling plates on the surface of the specimen and controlling it with a constant low-temperature water bath. From the test results, it was confirmed that our research method can quantitatively evaluate the decrease in erosion resistance of the vegetation specimen due to the freeze-thaw history.</p>
