| 摘 要： | 由于仅采用土舱压力控制土压平衡盾构平衡状态的方法存在缺陷,因此提出了在环境变化时调整土舱压力的新思路作为补充。这一新思路是针对土舱压力控制标准的不确定性、分析了土舱压力波动的原因后,形成了采用土压平衡比控制盾构平衡状态的辅助方法,这种新方法更有利于土舱压力的稳定。

| Abstract: | Owing to limitation to control balance of EPB shield only by earth chamber pressure,a supplementary method for control of earth chamber pressure when environment changed is put forward.Aimed at uncertainty of control norm of earth chamber pressure,the reason of fluctuation of earth pressure is analyzed,an additional method to control balance of shield by EPB balance ratio is given,which is more advantageous to stabilize earth chamber pressure. |
