摘要
以某高速公路的明星村作为降噪研究对象,采用NoiseSystem软件建立噪声预测模型,通过单一控制变量法对声屏障的设置参数进行优化设计,研究结果显示:在公路左侧设置高4 m、长250 m的声屏障后能使明星村所有敏感建筑物满足降噪要求。经现场实测数据验证,NoiseSystem软件可较好运用于高速公路声屏障工程优化设计中。
Taking the village beside a highway as an example,the noise prediction model is established by means of the software NoiseSystem.By using single variable control method,the parameters of noise barriers are optimized.Results of the study show that adding the noise barrier with a height of 4 m and a length of 250 m on the left side of the highway can satisfy the noise reduction requirements of all buildings in the Village.The in-situ measurement data verifies that the Noise-System software can be used in the optimization design of expressway noise barrier engineering.
