SOIL COMPACTION CHARACTERISTICS CONFIRMATION METHOD, AND EMBANKMENT COMPACTION MANAGEMENT METHOD
To provide a soil compaction characteristics confirmation method which can determine a maximum dry density of actual embankment materials including boulders with high accuracy even when utilizing results of soil compaction tests using easily-performed peak particle size samples.SOLUTION: A soil compaction characteristics confirmation method determining a maximum dry density of embankment materials comprises steps of: finding a compaction curve by conducting a soil compaction test using a peak particle size sample of an embankment material S4; converting the compaction curve into a normalized curve normalized by the maximum dry density of the peak particle size sample S5; determining a dry density obtained when the embankment material is compacted at a predetermined water content ratio and a predetermined energy as an actually measured dry density S7; and determining the maximum dry density of the embankment material by specifying a position of the actually measured dry density on the normalized curve S9.SELECTED DRAWING: Figure 1
【課題】容易に実施可能なせん頭粒度試料による土の締固め試験の結果を利用しても、巨礫を含むような実際の盛土材料の最大乾燥密度を精度よく求めることができる土の締固め特性の確認方法を提供する。【解決手段】盛土材料の最大乾燥密度を求める土の締固め特性の確認方法であって、盛土材料のせん頭粒度試料によって土の締固め試験を行うことで締固め曲線を求めるステップＳ４と、締固め曲線をせん頭粒度試料の最大乾燥密度で正規化した正規化曲線に変換するステップＳ５と、盛土材料を所定の含水比及び所定のエネルギーで締固めたときの乾燥密度を、実測乾燥密度として求めるステップＳ７と、正規化曲線における実測乾燥密度の位置付けを特定することで、盛土材料の最大乾燥密度を求めるステップＳ９とを備えている。【選択図】図１
