摘要：

在分析盾构掘进机的推进系统和刀盘系统的基础上,推导推进系统压力、刀盘系统压力、推进系统净流量与刀盘系统流量之间的关系,通过实验数据验证了推导模型的正确性.分析土舱内土体的流动连续性,得到螺旋输送机流量、刀盘系统流量、推进系统压力与土舱压力之间的1阶微分方程式,提出以推进压力、土舱压力和刀盘转速的实时数据采样值为输入,螺旋输送机转速为输出的基于排土控制的前馈反馈土压平衡模型.可知,土舱压力是由推进系统压力、刀盘系统流量和螺旋输送机流量多个因素共同决定的.实验表明,前馈反馈控制模型的控制效果较好.
Abstract:

Based on the analysis of thrust and cutter head system of shield machine, the relationship among the pressure of thrust and cutter head system, the flow rate of thrust and cutter head system was concluded and testified using the experimental data. A onestage differential formula including the flow rate of screw conveyor and cutter head system, the pressure of thrust system and soil room was concluded according to the analysis of liquid continuity of sealed soil room. Then a earth pressure balance model with forward-backward control method was built by detecting the real-time pressure of thrust system and soil room, the rotating speed of cutter head and controlling the rotating speed of screw conveyor. Results showed that the pressure in soil room was decided by the thrust pressure, the flow rate of cutter head and screw conveyor system. The control results of forward-backward control method are good.
