Abstract

The invention discloses a device and method for judging the fractured-rock-mass perfection degree. The problems that a fractured rock mass in the prior art cannot be sampled, and the perfection degreeof a fractured-rock-mass model simulated through similar materials cannot be determined are solved; the device and method have the advantage that a reference basis is provided for indoor-model mechanical test researching of a fractured rock mass with a perfection degree classifying method. According to the technical scheme, the device for judging the fractured-rock-mass perfection degree comprises a test platform for containing the fractured rock mass, angle-shape baffles, a supporting frame, side frames and a wave speed tester, wherein the angle-shape baffles are perpendicularly arranged relative to the test platform to limit the fractured rock mass; the supporting frame crosses the test platform, is connected with a vertical pressing part to apply normal pressure to the fractured rock mass, and is connected with a first transverse pressing part; the side frames are connected with a second transverse pressing part, and the first transverse pressing part and the second transverse pressing part apply confining pressure to the fractured rock mass; the wave speed tester is arranged on the side of the test platform.

Description

technical field [0001] The invention relates to the field of broken rock mass, in particular to a device and method for judging the integrity of broken rock mass. Background technique [0002] Broken rock mass is composed of many joints, fissures and structural planes, the continuity is very poor, the internal structure is easily damaged by disturbance, and the physical and mechanical properties are very complex. In actual engineering, the on-site integrity evaluation technology for broken rock mass has become mature, and its real physical state has been fully understood. Further in-depth study of its mechanical properties. [0003] Therefore, it is necessary to research and design the device for judging the integrity of the broken rock mass. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the present invention provides a device for judging the integrity of the broken rock mass, using ordinary concrete pouring modules, and stack...
