The thickness of layer-built EPS must not be increased in proportion to the magnitude of a rockfall, since the workability andeconomical efficiency become bad and irrational in case of a hugerockfall. In order to improve the performance of layer-built EPS weight free-fall tests were carried out on the layer-built EPS reinforced with Geogrids which were put between the EPS layers. It was found in this investigation that the layer-built EPS reinforced with Geogrids has a good performance against rockfalls., 落石を対象とした防災構造物(ロックシェッド)上に発泡スチロール(以後,EPSとする)を積層し,落石衝撃力を緩和する工法が一般的に行われてきた.落石衝撃力の緩和効果はEPS単体の積層構造で得られるが,衝撃力が大きくなると緩和領域(EPSの設置高さ)が大きくなり施工性や経済性が悪く不合理となることから,EPSの設置高をおさえて衝撃緩衝効果を高めることのできる工法が期待されている. 本研究では,実物大レベルの重錘落下実験によりジオグリッドを補強材として設置したEPSの衝撃緩衝効果が従来の設計方法より向上することを確認することができた., 金沢大学理工研究域環境デザイン学系}, pages = {213--220}, title = {EPSとジオグリッドの組合せによる落石衝撃力の緩衝効果に関する実験的研究}, volume = {25}, year = {2010} }
