摘要
针对交通建设项目环境影响评价中对大型立交的交通噪声污染特性分析不够系统和深入的问题,从占地面积、通行能力、行车速度、匝道转弯半径、车辆行驶状态等方面分析了大型立交的特性,从车流密度、速度、车型和行驶工况、路面材料、纵坡、距离、障碍物等方面分析了大型立交交通噪声的影响因素,提出了大型立交交通噪声具有立交位置和规模不同交通噪声影响不同、单车噪声相对较小、需要考虑加速和减速噪声、噪声声源复杂等特性。
Aiming at the problem that the analysis is not systematic and deep enough of the traffic noise pollution characteristics of the large-sized interchange in the environmental influence appraisal of the traffic construction projects,the article analyzes the characteristics of the large-sized interchange from the aspects of land occupation,traffic capacity,driving speed,turning radius of ramps and vehicle driving conditions,and analyzes the influence factor of the traffic noise of the large-sized interchange from the aspects of vehicle density,speed,vehicle type,driving condition,pavement material,slopes,distances and obstacles.The article puts forward that the large-sized interchange has the characteristics of the different influences of the traffic noise because of the different location and size of the interchange,relatively small noise of single vehicle,required to consider the noise caused by acceleration and deceleration and complexities of noise sources.
