A blasting vibration control prediction method based on a fault tree and a genetic algorithm

Abstract

The invention discloses a blasting vibration control prediction method based on a fault tree and a genetic algorithm, which collects all factors influencing the blasting vibration design and construction process in the history as fault tree events and constructs a blasting vibration fault tree. Identification of dominant factors; Genetic algorithm is used to optimize the initial weights and network structure of the neural network to replace the general neural network initial weights and the random selection and blind selection of the network structure. Then the neural network algorithm is usedto fine-tune the network weights and search the optimal solution or the optimal approximate solution in the network structure; constructing a BP artificial neural network model; predicted results: within the control range (1, 0, 0, 0); reaching the critical value (0, 1, 0, 0); exceeding the control value (0, 0, 1, 0); seriously exceeds control value (0, 0, 0, 1). The invention controls the occurrence of the blasting vibration accident from the source, and effectively reduces the harmful effect caused by the blasting vibration. The rationality and scientificity of blasting design are improved.

Description

technical field [0001] The invention relates to the technical field of engineering blasting, in particular to a method for controlling and predicting blasting vibration based on fault trees and genetic algorithms. Background technique [0002] With the rapid development of my country's engineering project construction and continuous improvement of technology, new technologies such as engineering blasting have been widely used in a large number of engineering construction fields such as mining, hydropower engineering, road traffic, nuclear power plant construction, and comprehensive development and utilization of underground space. Many major achievements have greatly promoted the progress and innovation of blasting technology. However, while engineering blasting brings speed and efficiency to engineering construction, due to the blasting vibration effect, it also leads to negative effects such as vibration, pollution, and noise on the surrounding environment, and even enginee...
