Abstract
This paper intends to address the blasting vibration problem during the construction of un-derground water-sealed petroleum storage caverns.The study adoptsthe ANSYS/LS-DYNA finite element software in combination with the field measured data to simulate the blasting process of adjacent caverns,and investigate the dynamic response of neighboring caverns under blasting loads.The results show that the vibration velocity errors in all directions at the measuring points are all within 10%,with a maximum error of 9.01%,indicating that the numerical simulation results are in good agreement with the field mo-nitoring results.The vault,arch foot and arch haunch are mainly subjected to tensile stress,while the cavern floor is dominated by compressive stress.On the monitoring cross-section,the peak displacement on the blast-facing side is 5.8-17.6 times that on the opposite side,revealing the dynamic response char-acteristics and vibration-induced failure mechanism of the adjacent cavern structure under the combined action of blasting loads.关键词
