Disclosed is a confined high-strength concrete support system applicable to an underground tunnel, comprising: multiple confined concrete arches (14); an anchor (1-2); an anchor cable (1-1); and a prestressed concrete steel strand backfill system. All the confined concrete arches (14) support surrounding rock (1-3) in a tunnel. The confined concrete arches (14) are sequentially arranged, and the adjacent confined concrete arches (14) are connected by means of a longitudinal connection mechanism. In the supporting system, multiple wire meshes (31) are arranged at a surrounding rock side and a tunnel side. Concrete is injected over the support system and the wire meshes (31). The prestressed concrete steel strand backfill system comprises a prestressed concrete steel strand system and a filling material (5). The prestressed concrete steel strand system refers to steel strands (1-4) connecting the arches with the anchor and the anchor cable. The steel strands (1-4) sequentially pass through ...

A multi-functional true triaxial rock drilling test system and method. The method comprises: acquiring rock cores from multiple drilled holes on a same test subject (6); performing a uniaxial test and a triaxial test on the rock cores, respectively, to obtain multiple sets of mechanical property parameters; obtaining, from a true triaxial rock drilling test system capable of directly measuring drilling parameters, multiple sets of drilling parameters; and establishing a relational expression between the mechanical property parameters and the drilling parameters. Thus, by using the relational expression, mechanical property parameters of a rock can be obtained merely by detecting drilling parameters of the rock. The multi-functional triaxial rock drilling test system is used for a predetermined test device to perform true triaxial loading on the test subject (6). Accordingly, the test device is capable of simulating a drilling process of a drilling apparatus experiencing a triaxial confining ...
