摘要:
钢弹簧浮置板是目前地铁工程中广泛应用于特殊减振地段的轨道结构。在实际工程建设中，受机器状态、地质情况以及操作人员水平限制等因素的影响，盾构施工的区间隧道往往会产生较大偏差，导致钢弹簧浮置板轨道结构高度不足，甚至调线调坡后仍然存在轨道结构高度不足的问题。因此，需要改变钢弹簧浮置板的结构尺寸或隔振器布置方式来解决该问题，同时也带来了钢弹簧浮置板减振性能的改变。以合肥某地铁工程为依托，利用有限元方法对特殊结构尺寸、特殊隔振器布置方式下的钢弹簧浮置板结构进行了模态分析，获取了其在不同工况下的振动特性。
Abstracts:
Steel spring floating slab track is a kind of track structure widely used in special vibration damping areas for metro engineering. In actual constructions, due to the influences of machine state, geological condition and operator level limit, large deviations often occur in the interval tunnels with shield construction, which leads to insufficient orbital height of steel spring floating slab track. This problem exists even after the slope adjustment. Therefore, it is necessary to change the structural size of steel spring floating slab track or the layout of vibration isolators, but at the same time, it also brings the change of vibration reduction performance of steel spring floating slab track. Based on a metro project in Hefei City, the finite element method is used to conduct a modal analysis of steel spring floating slab track structure in special structural dimensions and special vibration isolator arrangement schemes, so as to obtain the vibration characteristics of slab track under different working conditions.
