Abstract

The invention discloses a soil and structure contact surface testing machine. The soil and structure contact surface testing machine comprises a body frame, a structure panel, an X-direction motion system, a Y-direction motion system, a Z-direction motion system, a hydraulic loading and control system, a data acquisition system, a confining pressure chamber system, a temperature control system andthe like. The soil and structure contact surface testing machine is specially designed for researching the problem of the soil and structure contact surfaces, and can complete the research on the problem of the contact surfaces between various soil types, such as clay, fine-grained soil and coarse-grained soil and all kinds of structural panels under various saturation or non-saturation temperature field conditions. The normal stress is directly applied to the contact surfaces during the test. The concept is clear and the stress state is clear, the uniform strain of the soil can be ensured, the strain localization phenomenon is eliminated, the constant areas of the contact surfaces are ensured, and it is ensured that the results are true and reliable.

Description

technical field

[0001] The invention relates to a three-dimensional testing machine for the interface between soil and structure, and belongs to the technical field of soil engineering testing instruments. Background technique

[0002] The study of the mechanical properties of the contact surface between the soil and the structural panel is one of the important topics in the study of soil mechanics, which has a great impact on the calculation, design and construction technology of the structure. There are mainly two methods for the study of the mechanical properties of the contact surface between the soil and the structural panel, the experimental method and the numerical method. At present, the main test instruments used in the test method are direct shear tester, single shear tester, torsional shearer, dynamic triaxial tester and resonance column tester. Among them, the direct shear tester and the single shear tester are two types of contact surface test instruments that ...
