Application of Steel-spring Floating-slab Track to Vibration Reduction of the Metro and Building Integrated Structures
Based on the theory of vehicle -track coupling dynamics and dynamic finite element , and combined with an integrated project case of metro along with public buildings in soft soil ,the key influence factors of fundamental frequency optimization of steel -spring floating-slab track are discussed , conducting the analysis regarding the vibration level of time and frequency domain of inte -grated-structure vibration acceleration aroused by subway ,with its general idea is proposed as well. That is to say ,the reasonable natural frequency of steel -spring floating track should be determined at first,according to the natural vibration characteristics aiming at different integrated -structure types; and then,in the light of engineering experience and actual conditions ,the design parameter combinations of this track structure with high durability and safety , including the size of floating slab, spring rate and damping as well as arrangement space ,can be put forward without changing the opti -mum natural frequency.
