SOIL PROPERTY MEASURING METHOD AND SOIL PROPERTY MEASURING DEVICE
To provide a soil property measuring method and a soil property measuring device allowing improvement of efficiency.SOLUTION: Electric resistance of a ground material S is measured in an electric resistance measuring process. Dry density of a soil part of the ground material S is derived, in a soil part dry density derivation process, through the electric resistance of the ground material S measured in the electric resistance measuring process and a predetermined relation between an electric resistance of the soil part where gravel fractions/stones G are removed from the ground material S and dry density. Dry density of the ground material S is derived, in a total dry density derivation process, based on the dry density of the soil part of the ground material S derived in the soil part dry density derivation process, density of the gravel fractions/stones G of the ground material S, and content percentage of the gravel fractions/stones as a mass ratio of the gravel fractions/stones G in the mass of the ground material S. This allows labor saving in an indoor test and improvement of efficiency because of no need for acquiring electrical conductance per grain size and content percentage of the gravel fractions/stones G in the ground material S during the indoor test.SELECTED DRAWING: Figure 3
【課題】効率を向上できる土質測定方法及び土質測定装置を提供する。【解決手段】電気抵抗測定工程により、地盤材料Ｓの電気抵抗が測定される。土部分乾燥密度導出工程により、電気抵抗測定工程で測定された地盤材料Ｓの電気抵抗と、地盤材料Ｓから礫分・石分Ｇが除去された土部分の電気抵抗と乾燥密度との予め規定された関係とによって、地盤材料Ｓの土部分の乾燥密度が導出される。全体乾燥密度導出工程により、土部分乾燥密度導出工程で導出された地盤材料Ｓの土部分の乾燥密度と、地盤材料Ｓの礫分・石分Ｇの密度と、地盤材料Ｓの質量に対する礫分・石分Ｇの質量の比である礫分石分含有率とに基づいて、地盤材料Ｓの乾燥密度が導出される。これにより、室内試験において地盤材料Ｓにおける礫分・石分Ｇの粒径及び含有率ごとに検量線を取得する必要がないため、室内試験の省力化を図れ、効率を向上できる。【選択図】図３
