毕业设计 设计题目（中文）题目（外文）Design of Noise Control in Typical Sensitive Area of a High - speed Railway  某高速铁路典型敏感区噪声治理设计 摘 要 近年来，铁路交通发展迅速，但同时也给环境造成了一定的影响，其中铁路噪声为最主要的影响。铁路噪声直接影响了人们的休息、工作和学习，损害了人们的身心健康，其对声环境敏感区的影响更加明显。随着客运专线的出现，铁路沿线的环境要求也越来越高，因此如何减小铁路客运专线噪声对沿线的声环境敏感区的影响成为亟待解决的问题。 本次设计依据相关法律法规，进行噪声预测，确定对敏感区的噪声治理设计为设置声屏障。通过对声屏障的位置、插入损失的计算确定声屏障的高度，考虑经济性和实用性确定声屏障的材料与构型。最后对声屏障的工程造价进行经济评估。 关键词：高速铁路，噪声预测，声屏障  DESIGN OF NOISE CONTROL IN TYPICAL SENSITIVE AREA OF A HIGH - SPEED RAILWAY Abstract In recent years, the rapid development of railway traffic, but also to the environment caused a certain impact, including railway noise as the most important impact. Railway noise has a direct impact on peoples rest, work and study, damage peoples physical and mental health, its impact on the sound environment sensitive area is more obvious. With the emergence of passenger dedicated lines, the railway along the environmental requirements are getting higher and higher, so how to reduce the railway passenger line noise on the sound environment along the sensitive area has become an urgent problem to be solved. This design is based on the relevant laws and regulations, noise prediction, to determine the noise zone design for the sensitive area to set the sound barrier. The sound barrier is determined by the determination of the position of the sound barrier and the insertion loss, and the material and configuration of the sound barrier are determined by considering the economy and practicability. Finally, the economic evaluation of the cost of the sound barrier.
