Abstract

Provided are a visible transparent soil model test box with an adjustable surrounding rock pressure and a manufacturing method therefor. The visible transparent soil model test box includes pressure plates, force transferring plates, bolt assemblies and pressure boxes. The model box is assembled by the bolt assemblies, and then transparent soil is poured into the box. During the pouring of the transparent soil, the pressure boxes are buried inside the transparent soil and at inner sides of a left pressure plate, a right pressure plate and an upper pressure plate. After the transparent soil is consolidated, nuts are screwed to push the force transferring plates and the pressure plates by pressure gaskets to move inward to squeeze soil mass, and the pressure is controlled through readings of the pressure boxes, thus achieving automatic regulation of the surrounding rock pressure.
