摘要

类矩形盾构采用双辐条式圆形大刀盘加两个偏心刀盘的组合切削形式,刀盘受力状态复杂。为了研究掘进过程中各刀盘推力的变化,提出了一种基于与有限元分析相结合的在线检测方法。首先建立刀盘推力和扭矩的计算模型,结合有限元分析确定胸板上应力测点的位置,得到刀盘推力和测点应力之间的关系。然后,搭建刀盘应力采集系统,获取盾构掘进过程中测点的实时应力状态,与仿真结果进行对比,推导出刀盘的实际推力以及推力在各刀盘的分布状态。实验结果表明:该方法可实时检测类矩形盾构施工时各刀盘的推力,为盾构机刀盘的结构设计和安全操作提供理论指导和参考依据。

Abstract

The quasi-rectangular shield machine adopts the combined cutting form of two large circular spoke type cutter heads and two eccentric cutter heads whose force state is relatively complex. In order to investigate the thrust fluctuation of each cutter head,an in-situ detection method based on finite element analysis was proposed. Firstly,the calculation models of thrust and torque of cutter heads were established. By using the finite element analysis method,the relationship between the thrust of cutter heads and the stress of the detection points on the chest plate was obtained. By using the collected stress system,the realtime stress status of each detection point under the construction process was obtained. And then the actual thrust of the cutter heads and the thrust distribution of each cutter head were also derived by comparing the stress status with the simulation results.The experiment result shows that this method can measure the thrust of each cutter head in real-time,which provides theoretical guidance and reference for the structure design and safe operation.
