分析TBM转向过程,给出了TBM转弯时主机中心与隧道中心偏移量的计算公式,进而提出对支撑系统油缸行程的要求,为TBM支撑系统的设计提供依据。 The TBM steering process is analyzed. The formula for calculating the offset between the center of the host and the tunnel when the TBM is turned is given. Then the requirements for the cylinder stroke of the support system are put forward, which provides the basis for the design of the TBM support system.
