Abstract

粗粒子を多量に含む土質材料を扱う機会の多い今日, こうした粗粒土の密度管理が実施工において重要な問題になってきている. 粗粒土の締固め密度を推定する方法には, これまでに種々の方法が提案されている. 本論文では, それらのうちで特に密度補正式を用いて推定する方法を取り上げ, 諸家の実測データを基に詳細な比較検討を行っている. その結果, 主要な各提案式の得失を明確にして示すとともに, 福本の提案式がどの土質材料に対しても概ね精度良く適合し, 実務的に最も利用し易い式として推奨できることを明らかにしている.

This study highly focused on the methods using equation for estimating the compacted density of granular soils with oversize particles, and several equations indicated in past studies were explained. They were compared and examined in detail based on the data measured in the past, and the practical effectiveness and fitness were evaluated. Consequently, the equation proposed by Fukumoto was proved to be adaptable in good accuracy for any granular soils and most practical.
