防止飞机噪声扰民是机场项目环境影响评价工作的重要任务之一。在机场选址、预可行性研究等项目前期论证阶段开展环境可行性论证既及时又必要。从场址、跑道构型优化设计等方面对机场飞机噪声影响开展研究,提出:首先应结合净空、地形条件等因素,尽可能地拉大场址与相邻城市规划区的空间距离;其次应优化跑道构型,尽可能使跑道不正对城市规划区,以达到减少飞经城市规划区飞行量的目的。经过对机场场址、跑道构型的优化,飞机噪声对邻近城市区域的影响可以得到预防。 Preventing aircraft noise from disturbing people is one of the important tasks in the environmental impact assessment of airport projects. It is both timely and necessary to carry out the feasibility study of the environment in the stage of pre-feasibility demonstration such as airport site selection and pre-feasibility study. From the aspects of site and runway configuration optimization design, the paper studies the impact of airport aircraft noise, and puts forward that firstly, the space distance between the site and the adjacent urban planning area should be widened as much as possible according to the factors such as clearance and topographical conditions; Optimize the runway configuration, as far as possible so that the runway is not aligned with the urban planning area, in order to achieve the purpose of reducing the amount of flight through the urban planning area. After the airport site and runway configuration optimization, the impact of aircraft noise on the adjacent urban areas can be prevented.
