ZJ Strain-controlled direct shear (electric three-speed)
简要描述： This instrument is used to measure the shear strength of soil. By using four samples, under different vertical pressures, apply horizontal shear force for shearing, and obtain the shear stress at failure. Then the shear strength parameters, internal friction angle and cohesion of the soil are determined according to Coulomb's law.
产品介绍
I. Overview
ZJ-type strain-controlled direct shearing instrument is one of the main products of our company. It is the main conventional test instrument for the current geotechnical test. TB10102-2010 "Geotechnical Test Regulations for Railway Engineering", GB/T50123-2019 "Geotechnical Test Method Standard".
2. Main use
This instrument is used to measure the shear strength of soil. By using four samples, under different vertical pressures, apply horizontal shear force for shearing, and obtain the shear stress at failure. Then the shear strength parameters, internal friction angle and cohesion of the soil are determined according to Coulomb's law.
