Numerical study on the effect of in-situ stress on smoothwall blasting in deep tunnelling被引量：3
《Underground Space》2023年第4期96-115,共20页Xudong Li Kewei Liu Jiacai Yang Yanyan Sha Ruitao Song 
the financial support from the National Natural Science Foundation of China(Grant no.51974360)for carrying out this research work.
In the present study,a numerical model is first calibrated against the crack networks and pressure attenuation data in laboratory blasting test.Then,based on the calibrated numerical model,two-hole plane models are de...
