Abstract

The invention discloses a rock mass structural surface shear failure surface morphology evolution law system. The system comprises the steps of: performing literature lookup, field investigation and survey, data information arrangement and analysis and rock sample collection and processing; performing a conventional rock mechanics experiment; performing experimental test operation, three-dimensional physical model experiment, FLAC and PFC data simulation and theoretical analysis operation; carrying out operation analysis on the deformation characteristics of a rock mass under heavy rainfall infiltration-mining unloading; analyzing a fractured rock mass structural surface damage mechanical model and a fracture evolution mechanism; establishing a fractured rock mass nonlinear rheological model and analyzing fracture instability; and revealing the fracture instability mechanism of the fractured rock mass of a high and steep rock slope under the coupling of rainfall infiltration and mining unloading. The system has the advantage that safety control and stability evaluation of a mine slope are facilitated.

Description

Technical field [0001] The present invention relates to the field of geological technology, specifically a rock body structure surface shear destruction surface morphological evolution regular system. Background technique [0002] The mining industry is the engineering area of ​​raw materials and energy is the basis of the national economy. 80% of my country's metallurgical mine is from the open-air mining, and the open-air mine is of great significance to the sustainable development of my country's metallurgical industry. After decades of high-intensity mining, most large and medium-sized open-air mines in my country entered the deep concave mining stage, and some mines have been transferred to the underground mining stage. In the 21st century, with the rapid development of mine rock mass engineering technology and modern machinery equipment, the scale and depth of mine rock mass project continued to grow, the depth of 400m, the slope angle is greater than 40 ° large high-tech e...
