METHOD, PROGRAM, AND SYSTEM FOR DISCRIMINATING SOIL PROPERTY
To provide a method, program, and system for discriminating soil property, capable of estimating a humic acid content rate in soil easily with high accuracy.SOLUTION: The method includes: a stress application process for applying shear stress to a soil sample; a yield strain acquisition process for acquiring a yield strain being a shear strain in a boundary between a first state and a second state when the soil sample is shifting from the first state for elastic deformation into the second state for non-elastic deformation by the shear stress; and a humic acid content rate estimation process for estimating a content rate of humic acid in ground to which the soil sample belongs with the use of the yield strain.SELECTED DRAWING: Figure 9
【課題】簡易かつ高精度に地盤のフミン酸含有率を推定することが可能な、土質を判別するための方法、プログラム、及びシステムを提供する。【解決手段】土試料に剪断応力を印加する応力印加工程と、剪断応力によって、土試料が弾性変形する第１状態から、非弾性変形する第２状態に移行しようとするときに、第１状態と第２状態との境界における剪断歪である降伏歪を取得する降伏歪取得工程と、降伏歪を用いて、土試料が属する地盤におけるフミン酸の含有率を推定するフミン酸含有率推定工程と、を含む。【選択図】図９
