安徽宁国市梅岭隧道工程地质问题研究

摘要

By comparing scheme 3 and scheme 4 for the Meiling tunnel, with measured data from the field, this paper analyzed structural and deformational features of the Meiling tunnel and its neighborhood, described the joint, fault and wallrock occurrence features of intrusions it involves, then discussed their effect on the tunnel stability and possible en-gineering geological hazards that may occur as the result, finally put forward several issues needing attention in design and construction of the tunnel.%　　通过对梅岭隧道方案3和梅岭隧道方案4的比较研究，从野外测量得出的数据分析了梅岭隧道及其周围的构造特征和变形特性。阐明了梅岭隧道所涉岩体的节理特征、断层特征以及围岩产状特征，从而分析它们对隧道稳定性的影响和由此可能产生的各种工程地质灾害，并且提出了在设计、施工梅岭隧道时应注意的几个问题。
