摘要
通过结合小净距隧道三维开挖的模拟计算,研究两隧道掌子面间距离的变化对小净距隧道结构特别是中夹层稳定性的影响,得出了小净距隧道空间相互影响效应以及小净距隧道相邻两隧道掌子面间的合理距离。
By the study of 3D-excavation of twin-bore tunnel with small spacing especially for stability of middle rock pillars, the paper clarifies the interaction of twin-bore tunnel with small spacing and gives the reasonable interval between the cutting faces. This analysis provides the scientific bases and technical guidance for the construction of Jiuling Tunnel.
