摘要
隧道掘进机(TBM)与地质因素关系十分密切,隧道地质环境的优劣、岩石的强度、岩石的耐磨性及岩体结构面发育程度等,是决定是否选用TBM,以及TBM效率能否发挥的主要影响因素。本主讨论了它们的关系,采用TBM隧道工程的地质工作重点。同时对采用硬岩TBM掘进的秦岭特长隧道的TBM工作条件等级划分及TBM行为预测提出了作者的意见。
TBM tunneling performance has a close relationship with geological conditions, such as rock strength ,rock abrasion resistance,features of structural planes of rock mass,which are the main factors affecting the efficiency of TBM ,even the decision of adoption of TBM. The paper presents their relationship and focal points of geology survey as well as the suggestions on the classification of surrounding rock for the TBM construction of Qinling Tunnel.
