In order to diminish this discrepancy, curve-fitting through programming can be performed to check the design parameters of shield lining segments. 为了减小该偏差值，通过编制程序进行曲线拟合，验证盾构管片的设计参数。
A new technique is practiced in the EPB shield tunneling construction,which erected the ring in whole on the ground and then hung the ring down to the tunnel. 盾构管片在地面上拼装成环后再吊下组装是此前没有见诸报道的新工艺。
