摘要
通过Ｘ射线粉晶衍射成分分析，结合岩石点荷载强度试验研究，查明国内外首次发现的此隧道部分砂质泥岩发生岩爆活动的内在原因。
Through the X-ray diffraction analysis and point loading strength test, intrinsic causes for the rockburst in some sandy mudstones in Erlang mountain highway tunnel has been ascertained. This kind of rockburst phenomenon is first discovered at home and abroad.
