  • MULTI-FUNCTIONAL STRATIGRAPHIC STRUCTURE MODEL TESTING SYSTEM AND TESTING METHOD
    Publication number: 20210327307
    Abstract: Provided are a multi-functional stratigraphic structure model testing system and testing method. The system includes a test piece testing device platform that includes a watertight fan-shaped closed cavity, a fluid-solid coupling loading system, and an anti-arc reaction frame system. A coupling loading system region consist of hydraulic (liquid) loading and multi-directional solid-skeleton loading onto a pore or crack test piece, which can be independently operated or combined with each other's. The fan-shaped closed cavity is fixed through the anti-arc reaction frame system, and a fan-shaped center region is provided with an application region of underground working face. The other two flat fan sides are provided with application regions of physical and chemical improvement for surrounding rock.
