Abstract

The invention discloses a blasting peak speed prediction method and device based on RGA-BPNNG and a medium. The method comprises the steps that blasting characteristic parameters of a to-be-blasted area are acquired; according to the blasting characteristic parameters and a preset random GA-BP neural network group blasting peak speed prediction model, predicting the blasting peak speed of the to-be-blasted area, wherein the preset random GA-BP neural network group blasting peak speed prediction model is obtained by training a random GA-BP neural network group through historical blasting characteristic parameters of a blasted area. The blasting peak speed after blasting in the to-be-blasted area is predicted, blasting characteristic parameters can be reasonably adjusted and designed conveniently, and it is guaranteed that the blasting effect after blasting meets the working condition requirement; according to the method, the blasting peak speed is predicted by the random GA-BP neural network group blasting peak speed prediction model, so that the precision and reliability of the blasting peak speed prediction value are effectively improved.

Description

Technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a method, device and medium for predicting peak blasting velocity based on RGA-BPNNG. Background technique [0002] The maturity of engineering blasting technology and its wide application in the field of engineering construction have become an indispensable and important construction method. While bringing huge economic and social benefits, various harmful effects produced by blasting operations also affect the lives and safety of buildings and personnel around the project area. Among them, the impact of blasting vibration is the most significant: building cracks, door and window vibration, and slope landslides are common harmful effects of blasting vibration. Therefore, the demand for accurately predicting the intensity of blasting vibration is becoming more and more urgent. Peak blasting velocity is a direct parameter that reflects the intensity of blasting vibrat...
