摘要

通过在北京地铁某车辆段库内第20股道上原位换铺9种轨道结构，对比分析了8种不同轨道减振结构的减振效果以及上盖二次结构噪声的降噪效果，并根据结构振动与结构噪声的测试数据，对照分析了结构振动与二次结构噪声的关系，验证了根据结构振动预测二次结构噪声的预测公式。研究指出：车辆段上盖建筑内由列车通过引起的结构振动和二次结构噪声在频域上具有高度的一致性，同时二次结构噪声可依据楼板的振动速度进行预测；由于计权方式、计算频率等方面的差异，振动减少量和结构噪声的减少量在数值表达上存在差异；实际工程中应根据实际的振动和噪声频谱特性选择合理的轨道减振措施。

Abstract

9 kinds of track structures were tested at the original position of the 20th track in a depot of Beijing Metro.The vibration reduction effect of 8 kinds of track structures and the denoising effect of secondary structure noise indepot’s superstructure were analyzed contrastively.According to the test data of structural vibration and structural noise, the relationship between structural vibration and secondary structure noise was analyzed, and the prediction formulafor secondary structure noise based on structural vibration was verified.The research indicated that structural vibration and secondary structure noise caused by train passingin superstructure of subway depot have high consistency in frequency domain; secondary structure noise can be predicted according to vibration speed of floor; due to differences of weight calculation methods and frequency calculation ones, there are differences in numerical expression of vibration reduction value and structural noise reduction one;in practical engineering, reasonable track vibration reduction measures should be selected according to the actual vibration and noise spectral characteristics.
