| 摘 要： | 随着城市的发展,交通噪声日益严重,沿街布置院落式建筑是改善道路两侧用地声环境的重要措施之一,院落的建筑高度、开口尺寸及后退道路红线距离等因素是影响措施成效的重要因素。本文选择典型研究区域,根据声音的不同传播方式,合理布置测点,现场测量车流量及声压级,并将这些数据输入计算机模型,对模型进行验证。在保证模型精度的情况下,对不同建筑形态变化的院落内部声环境进行模拟发现:随着建筑高度的增加、沿街开口宽度的减小,以及建筑后退道路红线距离的增加,沿街院落内部的声环境会得到明显改善,且建筑高度在6 m以内、开口宽度在12 m以内、建筑后退道路红线距离9 m以内效果较明显,当超出确定范围时效果不明显。本文的研究可为改善沿街院落的声环境提供理论支持。

| Abstract: | With the urban development,the impact of traffic noise has become more and more serious.Designing courtyard-style buildings alongside streets is one of the important measures to improve the sound environment for both sides of streets.The courtyard-style buildings' height,opening size,and the backward distance from curb are important factors.In this paper,taking a typical area as the study object,the measurement points were arranged according to the different modes of sound transmission,and the traffic volum... |
