Blast damage zone strength reduction method for deep cavern excavation and its application
《Frontiers of Structural and Civil Engineering》2024年第2期236-251,共16页Tianzhi YAO Zuguo MO Li QIAN Yunpeng GAO Jianhai ZHANG Xianglin XING Enlong LIU Ru ZHANG 
the financial support from the National Natural Science Foundation of China(Grant No.U1965203).
The drill and blast(D&B)method is widely used to excavate underground spaces,but explosions generally cause damage to the rock.Still,no blast simulation method can provide computational accuracy and efficiency.In this...

Prediction of characteristic blast-induced vibration frequency during underground excavation by using wavelet transform被引量：2
《Frontiers of Structural and Civil Engineering》2022年第8期1029-1039,共11页Tae Un PAK Guk Rae JO Un Chol HAN 
The authors are grateful for the financial support received from the National Science and Technical Development Foundation of DPRK Korea(No.24-210301).
Blast-induced vibration produces a very complex signal,and it is very important to work out environmental problems induced by blasting.In this study,blasting vibration signals were measured during underground excavati...
