摘要
针对市域快线实际运营条件,优化了钢弹簧浮置板轨道方案,并建立了钢弹簧浮置板轨道有限元模型,分析了振动性能和减振效果,计算结果表明,优化后钢弹簧浮置板方案减振效果达18 d B以上,钢轨动态下沉量满足相关规范的要求,市域快线特殊减振地段采用钢弹簧浮置板是可行的。
In light of actual operation conditions of urban expressway, the paper optimizes steel-spring floating slab track scheme, establishes fi-nite element model of steel-spring floating slab track, and analyzes vibration performance and damping effect. Results show that： the damping effect of the optimized steel-spring floating slab scheme is over 18dB; dynamic steel track settlement meet demands; applying steel-spring floating slab in special urban expressway damping section.
