Abstract: Abstract During the blasting excavat.ion process of the underground cavern, the layers below the top arch layer are usually excavated with vertical holes in the ladder section. Based on the dynamic theory of blasting impact, the finite element analysis software ls-dyna and COMSOL are used to determine the dangerous points in the process of open-cut and under-cut and the blasting point with the greatest impact on the building according to the design scheme of ground storage tanks and buildings, and establish a blasting analysis Numerical model The vibration amplitude of the ground storage tank and the dynamic response of the storage tank during the blasting process of the maximum explosive quantity were analyzed, and the deformation and stress distribution of the foundation and storage tank were obtained; the maximum amplitude of the building during the blasting and excavation process was further analyzed, Evaluate the reliability of the blasting excavation process of buildings in underground caverns.
