Abstract

The invention relates to the technical field of rock fracture detection, and provides a rock fracturing fracture network topological structure depicting system, which comprises a detection shell. A memory, a processor and a computer program which is stored in the memory and can run on the processor are arranged in the detection shell. When the processor executes a computer program, the following steps are realized: acquiring rock in-place images at different deformation moments by adopting image equipment, and acquiring in-place sub-pixel crack spatial distribution based on each image; by adopting the technical scheme, image boundary conditions do not need to be simplified, different results caused by different structural discretization forms are avoided, and inherent crack information isnot contained; the rock fracture network can be effectively depicted, and the whole rock fracture network expansion process is obtained.

Description

technical field [0001] The invention relates to the technical field of rock fracture detection, in particular to a rock fracturing fracture network topological structure depiction system. Background technique [0002] Rock fracture is a common phenomenon in rock mass engineering. Studying the evolution law of rock fracture and predicting the time and location of rock fracture are very important for basic engineering construction, efficient development of natural resources, and understanding and evaluation of deep fault activation in the earth. The rock will produce discontinuous infrasonic waves in the process of deformation and failure, and the surrounding rock noise during the excavation process is monitored. The monitoring results show that the rockburst has significant temporal and spatial characteristics. [0003] It is one of the effective means to study the spatiotemporal effect of rock fracture through the extension of rock fracture network. Numerical simulation, fr...
