A ship lock excavation blasting vibration control method and system

This invention relates to the field of water conservancy engineering construction technology, and discloses a method and system for controlling blasting vibration during lock excavation. By collecting information on the geological hardness of rock strata and the distance to surrounding buildings, and combining this with finite element analysis to simulate the blasting energy distribution, a dynamic matching mechanism for borehole depth and charge quantity is constructed. This method overcomes the limitations of traditional empirical parameter settings and uses iterative simulation and optimization algorithms to achieve coordinated adjustment of borehole depth and charge quantity. For example, in areas with high rock hardness, by increasing the borehole depth and matching a segmented charge strategy, the blasting energy is uniformly released in the deep rock mass, effectively reducing the peak ground vibration and avoiding structural damage to adjacent buildings. Furthermore, by introducing multi-dimensional data analysis and multi-scenario simulation verification mechanisms, it can flexibly cope with complex working conditions such as uneven rock hardness, topographical undulations, adjacent water bodies, or dense building clusters.
