noun
angle of shearing resistance
Technical term in soil mechanics and geotechnical engineering; refers to the angle whose tangent is the coefficient of internal friction of a soil.
砂質土のせん断抵抗角は、一般に30度から40度の範囲にある。
The angle of shearing resistance of sandy soils is generally in the range of 30 to 40 degrees.
Standard kanji spelling for this technical term.
Alternate kanji form using 剪 instead of せん; less common but still used in technical contexts.
Often used interchangeably with せん断抵抗角 in soil mechanics, though 内部摩擦角 strictly refers to the angle of internal friction.
Compound of せん断 (shearing) + 抵抗 (resistance) + 角 (angle).
