Abstract

The invention discloses a two-dimensional geotechnical model test device and method. The test device comprises a rectangular frame-shaped rack body, wherein two size adjusting plates are arranged vertically side by side in the rack body; an adjusting plate backing plate is fixedly arranged at the lower part of the inner wall of each size adjusting plate; a chute is vertically arranged at the middle upper part of the inner wall of each size adjusting plate; a fixed model contact plate is vertically arranged inside each size adjusting plate; and the fixed model contact plate is in sliding contact with the chute on each size adjusting plate through a plurality of balls. The two-dimensional geotechnical model test device has the advantage of simple structure, easy assembly and disassembly, easy size adjustment, small frictional resistance, big rigidity and low manufacturing cost, and the detection means in the testing process is comprehensive and reliable.

Description

technical field [0001] The invention belongs to the field of physical test models, in particular to a two-dimensional rock and soil mechanics model test device and method. Background technique [0002] Physical model test is an important method for studying geotechnical engineering problems today. Physical simulation research on geotechnical engineering with complex geological conditions can analyze and predict the physical and mechanical characteristics of engineering prototypes, which is very important for solving practical engineering problems. practical value. During the test, similar materials are prepared according to the characteristics of the test target rock and soil, and then the similar materials are poured into molds according to the pouring design drawing, and finally the loading test is carried out on the model, and the data is observed and recorded through the instrument. Existing test devices often have disadvantages such as complex structure, difficult size...
