| 中文摘要 |
| 选取城市居住区中典型地下车库,在优化其出入口噪声采样点布置和同步采样点分组基础上,通过对噪声样本的声学分析,研究了车库出入口坡道噪声与坡道结构、坡度、线形、上下坡等相关因素的关系.通过对平直混凝土路面车库出入口噪声影响预测值的修正,建立了车库出入口坡道噪声影响预测模式.

| 英文摘要 |
| Some typical entrances/exits of the underground garages are chosen in urban residential areas. On the basis of the optimization of the positions of the noise sampling points and the groupings of the synchronous sampling points, by means of the acoustical analysis of the noise samples, the relation of the correlative factors, among the ramps' noise of the entrances or exits of the garages, the structure, grade, shape of the ramps, upgrade and downgrade, is studied. The prediction model of the ramp's noise influence of the entrance or exit of the garage is established through amending the noise influence of the entrance or exit of the even concrete road.
