摘要
岩爆是深埋长隧道的主要工程地质问题之一。影响岩石发生岩爆的主要因素有围岩性质、埋深、区域构造应力、地形地貌、活断层和地震等。文中对上述因素对岩爆的影响进行了分析,并指出精细的地面地质调查是合理评价深埋长隧道岩爆的基础。
Rock Burst is one of the main engineering geology problems of deep-lying long tunnels. The main factors, which affect the rock burst of deep-lying long tunnel, include surrounding rockmass property, upper rockmass depth, regional tectonic stress, topography and geomorphology, active fault, and earthquake,etc. On the basis of the analysis of the above factors on rock burst, this paper point out that careful geology investigation is a key point for the rational assessment of rock burst of deep-lying long tunnels.
