DIVERSITY AND EVOLUTION OF DRUG RESISTANCE MECHANISMS IN MYCOBACTERIUM TUBERCULOSIS


Numerical study of tunnel blasting parameter optimization and vibration damage based on the RHT constitutive model

To solve the optimization problem of blasting parameters and consider the influence of interaction between blastholes on the spatial distribution of surrounding rock damage, the Riedel-Hiermaier-Thoma constitutive model parameters of marble were first calibrated from numerical trial calculation and impact test.Then, the blasting excavation of a tun
