Intelligent model constructuring method for analyzing cavity wall rock stability

The invented method includes the following steps: firstly, defining object problem influence factor, selecting model structure, adopting orthogonal testing design or uniform testing design method to make optimization design for influence factor, sampling range and sampling frequency, then making finite element analysis of designed value to form main sample self-group of the intelligent model, making the main sample self-group undergo the process of characterization treatment, then utilizing the value obtained after characterization treatment to construct intelligent analysis model by utilizing neural network algorithm.
