根据多年大件运输的经验，针对TBM运输过程中刀盘、主轴承、主梁及刀盘支撑等超大超限件，系统地总结了可能制约TBM公路运输的诸多难题，例如路面宽度、高度限制，通行荷载要求，连续大坡度上下坡及转弯困扰等，从技术角度提出相应解决办法和措施，可供同行参考，以期顺利实施大件运输。

Problems in Highway Transporting Large-Type Equipment of TBM and Our Counter-Measures to Them

Upon the basis of our rich experience of many years in the transportation of large-type equipments, many difficulties arising in the course of transporting TBM, which may restrain the transportation of TBM on highways, are systematically summed up in the paper,with greater stress placed on the handling of extra-large parts of TBM, such as the cutting head, the main beam, cutting head supports and so on. The retraining factors include the width of the road,height limits, requirements in traffic loads, continuous slope uphill or downhill, taking a turn, etc. All those above-mentioned difficulties are technically solved, with some useful methods or suggestions put forward. The results of our practice may provide good references for peers so as to facilitate the transportation of extra-large equipments.
