Abstract:
In order to make the collapse process of chimney more accurate and avoid safety accidents, ANSYS/LS-DYNA was used to build a three-dimensional finite element model of 150m steel-concrete structure chimney and carry out numerical simulation on the directional overturn process of chimney. Blasting cut length as a variable, and through the equivalent stress, collapse collapse process after the critical pile length and width, capsized in the process of chimney at the top of the node displacement is analyzed, the results show that the numerical analysis will involve the process simulation of the chimney collapsed, according to the numerical simulation results can be optimized blasting parameters design, make the chimney collapse more accurate, it provides reference for blasting scheme design.
