| 摘 要： | 针对不均匀地层中盾构施工引起的刀盘振动问题,建立刀盘有限元计算模型,并基于振动结构模态分析理论,分析盾构刀盘的模态特性,得到刀盘振型分析的结果同盾构掘进中出现的实际问题现象相一致。另外,以模态分析的结果为依据,分别从刀盘底座直径及柔度变化的角度分析对刀盘模态的影响,提出增大刀盘模态的方法及对刀盘结构设计的建议,从而可避免由于刀盘所受冲击与振动所致的联接螺栓松动及联接部件裂纹。此设计建议可应用于其它盾构刀盘的结构设计中,具有较大的工程实用价值。

| Abstract: | Directed towards the problems of cutter disc vibration caused by shield construction in the nonuniform stratum,the finite element calculation model of cutter disc was established.On the basis of modality analytical theory of vibration structure to analyze the modality characteristics of the shielding cutter disc,thus obtained a consistent phenomena between the analytical result of cutter disc vibration mode and the practical problems appeared in the shield driving.Moreover,taking the result of modality anal... |
