COMPOSITION DETERMINATION METHOD OF PLASTIC GROUT MATERIAL

ABE TOMOHIKO

To provide a method for determining adequate compositions of the plastic grout material having properties suitable for each of construction sites.SOLUTION: A composition determination method of plastic grout material of the present invention comprises the steps of: measuring properties (e.g. grain size distribution, porosity n, and the like) of the constructed ground (e.g. boulder ground); calculating yield strength (τy) based on measured properties of the constructed ground; and determining compositions of the plastic grout material meeting a calculated yield strength (τy).SELECTED DRAWING: Figure 1

【課題】施工現場毎に対応した性状を持つ可塑性グラウト材料の適正な配合を決定する方法の提供。【解決手段】本発明の可塑性グラウト材料の配合決定方法は、施工対象地盤（例えば巨礫地盤）の性状（例えば、粒度分布や間隙率ｎ等）を計測する工程と、計測された施工対象地盤の性状から降伏応力（τｙ）を演算する工程と、演算された降伏応力（τｙ）を充足する可塑性グラウト材の配合を決定する工程を有している。【選択図】図１
