摘　　要：盾构推进系统中的推进分区压力控制是盾构向前掘进以及进行盾构姿态纠偏的重要手段。盾构推进液压缸普遍采用固定分区模式。以8 m级盾构为例,对推进液压缸分区中推进液压缸浮动分配策略对推进力心及力矩影响做对比分析。建议盾构推进系统设计时在保留原有的343分区的基础上融入363分区模式,以提高盾构在垂直方向上的纠偏能力。The thrust grouping pressure control in the thrust system of shield is an important means for shield to dig forward and for shield posture correction.The shield thrust hydraulic cylinder generally adopts a fixed grouping mode.Taking the8m shield as an example,the impact of thrust hydraulic cylinder floating allocation strategies in thrust hydraulic cylinder grouping on the thrust force center and moment is compared and analyzed.It is recommended that the shield thrust system shall be designed to incorporate the 363-grouping mode on the basis of retaining the original 343-grouping to improve the correction ability of the shield in the vertical direction.
