ActiveInstrument for soil test - Shear apparatus - Part 1: Strain-controlled direct shear apparatus
土工试验仪器 剪切仪 第1部分：应变控制式直剪仪
Application Summary AI generated
This standard specifies the technical requirements, test methods, and inspection rules for strain-controlled direct shear apparatuses used in geotechnical engineering. It is applied in laboratory soil testing to measure the shear strength parameters (cohesion and internal friction angle) of soil samples under controlled strain rates. The standard ensures consistency and reliability in soil mechanics testing for foundation design, slope stability analysis, and earthwork construction.
