Abstract

The invention discloses a straight cut testing system for rock and earth mechanics, relating to a cutting system. The invention is composed of outer frame, horizontal loading system, vertical loading system, cut box, and measuring system; the horizontal loading system, the vertical loading system, the cut box and the cut box are fixed on the outer frame, respectively; the horizontal loading system, the vertical loading system and the measuring system are connected with the cut box, respectively. The invention has high measuring accuracy and good stability; all the data are automatically collected, thus reducing artificial reading error; it adopts variable frequency electric motor so as to reduce the manufacturing cost on the premise of assuring a stable cutting speed; all the parts are removable, convenient to transport and install. It can be used in determining peak values and remaining shearing strength of fine earth, coarse earth and soft rock and provide strength parameter for engineering design and rock and earth stability.

Description

Technical field

[0001] The invention relates to a shearing system, in particular to a direct shear test system in the field of rock and soil mechanics testing, which can be used to determine the peak and residual shear strength of fine-grained soil, coarse-grained soil and soft rock, and is an engineering Design and stability analysis of rock and soil provide strength parameters. Background technique

[0002] Most of the damages of foundations and rock-soil buildings are shear failures. Therefore, accurate determination of the shear strength parameters of rock-soil masses is of great significance in geotechnical engineering construction. The instability and failure of geotechnical engineering is accompanied by the development of shear displacement. Therefore, in recent years, the method of testing the strength of rock and soil by applying shear force or shear displacement has received renewed attention all over the world. , The direct shear test is the most popular because of its...
