Abstract

The embodiment of the invention provides a method and device for calculating the vibration velocity of underwater drilling and blasting considering the internal structure of rock, an electronic deviceand a computer-readable storage medium, and relates to the technical field of vibration velocity calculation of underwater drilling and blasting. In the embodiment of the invention, the method includes the steps that firstly, blasting parameters for underwater blasting operation for the rock mass structure are obtained, wherein the blasting parameters include the maximum charge amount of a singlesection, a distance between blasting centers and an elevation difference; secondly, the first peak vibration velocity is calculated according to the blasting parameters and a preset first formula, and a second formula is established according to the first peak vibration velocity, wherein the second formula satisfies the normal distribution; and then, the blasting vibration speed for the underwater blasting operation is calculated based on the second formula and the preset second peak vibration speed. Through the method, the accuracy of blasting vibration velocity calculation can be improved.

Description

technical field [0001] The present application relates to the technical field of underwater drilling and blasting vibration velocity calculation, in particular, to a method and device for calculating underwater drilling and blasting vibration velocity considering the internal structure of rocks, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the vigorous development of my country's shipping industry, underwater drilling and blasting has been widely developed. The peak vibration velocity of underwater drilling and blasting is the most critical evaluation index in the response characteristics and dynamic stability evaluation of adjacent buildings (structures) under the action of blasting seismic waves. [0003] However, the inventor found that in the prior art, the research on blasting vibration velocity still stays at the stage of considering the controllable variables such as blast center distance, single-stage maximum charge...
