摘要
通过对诸永高速公路磐安段西华岭隧道围岩中凝灰岩岩体,开展了数值力学试验,在确定连续微元尺寸δc及各项基本力学参数的基础上,试验获得的序列不同尺寸岩体变形破坏过程声发射频率、声发射能量图,进一步描述了该围岩岩体的声发射特征。
This paper carried out a numerical experiment of wall rock masses from Xi Hualing Tunnel. After detennining the continuous micro - element dimension δc and the mechanical parameters, this paper described its sound emission characters based on sound emission frequency ＆ energy chart of rock destructive procedure.
