摘要
根据TBM掘进过程中得到的大量实测参数,建立相应的费希尔判别函数来对围岩状况进行反推,考虑刀盘转速、贯入度、扭矩和推力四个因素来判断围岩质量,进而对支护管片进行选择,应用于工程实际,取得了良好效果。
Based on a great deal of parameter data in TBM excavating process, this paper reversed adjacent rock condition taking advantage of discriminant function of Fisher model. Take revolution, penetration, torsional moment and thrust into account to estimate rock quality. Further-more choice can be made between two types of duct piece. Finally this method has been applied to practical project, and good effection has been achieved.
