| Summary: | With the advances of technology, TBMs are becoming more versatile and TBM tunneling has become a common tunneling method. During project planning, the prediction of TBM performance is a key factor for selection of tunneling methods and preparation of project schedules. During the construction, TBM performance need to be evaluated based on the encountered rock mass conditions and the machine parameters. A suitable prediction and evaluation model is required by the developer, contractors and TBM manufacturers. The objectives of this research are to study rock mass fragmentation mechanism induced by TBM cutters, and to develop a TBM penetration rate prediction model based on in situ measurements and laboratory tests. |
