Abstract

The invention discloses a soft-rock-like-simulated-roadway-project model test device. According to the soft-rock-like-simulated-roadway-project model test device, a model solid-liquid mixture is poured and solidified through a model cavity to form a model test piece, an upper pressing head of a triaxial test machine, a left loading assembly, a lower loading assembly and a right loading assembly are combined, the model test piece is pressed in multiple directions through a control system, and loading of the model test piece is achieved. The soft-rock-like-simulated-roadway-project model test device comprises the upper pressing head of the triaxial test machine, a back acrylic plate, a front acrylic plate, a frame assembly, handles, the left loading assembly, the lower loading assembly, the model cavity, the right loading assembly and the model test piece. The soft-rock-like-soft-rock-simulated-roadway-project model test device is easy to operate, and the application prospects are broad in deep soft rock project tests.

Description

Technical field [0001] The invention relates to a roadway engineering model experimental device, in particular to a soft rock-like simulated roadway engineering model experimental device. Background technique [0002] Deep soft rock engineering has always been a bottleneck project in underground engineering. With the advancement of science and technology, the research on deep mining of resources has increasingly important theoretical significance and practical engineering value. Because the existing three-axis testing machine can only be used for forming The specimens are subjected to axial pressure and confining pressure. In order to more realistically simulate the loading process of the roadway engineering and realize the multi-directional loading of the model specimens, a soft rock-like simulation roadway engineering model experimental device is designed. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a soft rock-like...
