Xiao Qinxue. An Experimental Study on Bolt and Shotcrete in Model Materials[J]. Journal of Civil and Environmental Engineering, 1997, 19(2): 94-99. DOI: 10.11835/j.issn.1674-4764.1997.02.014.
a series of bolts and shotcrete experiments are made with the model materials which have different soft structure surfaces
and their acting mechanism is discussed.The experimental results have some practical values of the bolts and shotcrete design in underground engineering.
