Heavy snowfall after the Mid-Niigata Earthquake further aggravated the problem. This paper deals the impact of heavy snow load on the foundations of defensive structures and discusses their weakening mechanism after the Mid-Niigata Earthquake. Geology of the study area is studied in detail. Geotechnical properties of the foundation materials are determined. The laboratory assessments of the effects of slaking on the behavior of mudstone, especially, the influence of degradation on strength resulting from gradual slaking are examined.}, pages = {25--39}, title = {新潟県中越地震とその後の豪雪による雪崩予防柵の被害に関する考察}, volume = {27}, year = {2005} }
