摘要
为提升江苏省高速公路声屏障的声学性能以及寿命,对江苏省高速公路沿线250 km已建声屏障进行全面调研,对声屏障现状特征进行分析,并对已建声屏障存在的问题进行分类总结,根据其发生概率以及影响程度进行重要性分级,从日常养护、结构养护、中期大修以及拆除重建4个方面提出针对性的解决对策。
In order to improve the acoustic performance and lifespan of the sound barriers on expressways in Jiangsu Province,a comprehensive survey of the 250 kilometers sound barriers along the highways in Jiangsu Province was carried out,the current characteristics of the sound barriers were analyzed,and the existing problems of the built sound barriers were classified and summarized.According to the probability of occurrence and degree of impact,the importance is graded.Finally,targeted solutions are proposed from four aspects:daily maintenance,structural maintenance,mid-term overhaul,and demolition and reconstruction.
