全断面硬岩隧道掘进机
全断面硬岩隧道掘进机-
全断面硬岩隧道掘进机（TBM）在长距离、大埋深硬岩掘进环境下会受到地应力的影响，导致岩石破碎机理发生变化，进而造成破岩效率低下及冲击载荷大的工程问题。
In long-distance , large-depth of hard rock tunneling project condition , the affection of crustal stress to TBM causes rock-fragmentation mechanism change and thereby leads to engineering problems like inefficiency rock-breaking and large impact load .
