摘要:
本文针对某机场航站楼及综合交通换乘中心(GTC)的实际工程项目,建立了列车-轨道空间耦合动力学模型、轨道-土体-建筑物三维有限元模型及建筑物结构噪声分析模型,评估了高速铁路及地铁行车所致振动对航站楼及GTC建筑物的影响,并分析了建筑物基础隔振措施的隔振效果。结果表明:采取基础隔振措施前,GTC建筑物内旅客过夜用房区域的最大Z振级和二次结构噪声分别达到74.4 dB和45.3 dB(A),航站楼建筑的最大Z振级和二次结构噪声分别为74.6 dB和46.6 dB(A),均超出了标准GB 10070-1988和JGJ/T 170-2009规定的限值。采取基础隔振措施后,GTC和航站楼内Z振级分别减小了6.5～10 dB和6～9.9 dB,二次结构噪声分别减小了9.8～11.2 dB(A)和6.4～10.5 dB(A),均满足标准GB 10070-1988和JGJ/T 170-2009规定的夜间限值。研究结果对于铁路与航站楼的综合开发建设具有实际指导意义。
Abstract:
A spatial train-track coupled dynamic model, 3D finite element models of track-soil-building system, as well as building structural noise analysis model are established to evaluate the structural vibrations and noises of airport terminal building and a ground traffic center(GTC)induced by high-speed and subway trains. The isolation effectiveness of building foundation isolation measures is also investigated. The results show that, before implementing foundation isolation measures, the maximum Z-vibration level and structural noise of the GTC building reached 74.4 dB and 45.3 dB(A), while those in the terminal building were 74.6 dB and 46.6 dB(A). All the values exceed the limits specified in the standard GB 10070-1988 and JGJ/T 170-2009. After adopting foundation isolation measures, the Z-vibration levels of the GTC and terminal were decreased by 6.5～10 dB and 6～9.9 dB respectively, and their structural noise was decreased by 9.8～11.2 dB(A)and 6.4～10.5 dB(A), both meeting the nighttime limits specified in standards GB 10070-1988 and JGJ/T 170-2009. The research findings have practical guiding significance for the integrated development and construction of railways and airport terminals.
