【摘要】 通过对鼓楼立交桥机动车流量的实测,运用高架桥交通噪声预测数学模型,对鼓楼立交桥交通噪声剖面分布和地面分布进行了分析。经过计算声程差,得出合理的利用声屏障技术来解决鼓楼立交桥交通噪声问题是可行的。更多还原

【Abstract】 By surveying flux of motor vehicles on Gu Lou intersection,applying viaduct traffic noise’s forecasting mathematical model,analyzing composition and influencing factor of city viaduct traffic noise,and analyzes the traffic noise’s spatial and surface distribution.Then calculating acoustic-path difference,It is shown that utilizing sound barrier approach is effectual to figure out traffic noise of Gu Lou intersection.更多还原
