【摘要】 文章对目前城市快速路两侧噪声严重的问题进行了分析,针对目前的隔声屏障成本造价高、易损坏及安装长度不够等问题,提出采用陶粉纤维加气混凝土砌块来制作隔声墙,创新性地采用吸声尖劈的方式来进行构造设计,使道路和隔声墙一体化设计施工,达到城市快速路的吸声隔声减噪之目的。更多还原

【Abstract】 The problem of noise is serious on sides of city expressway. Facing the real problems of the sound proof screen like high-cost, easy to damage, and not enough installation length, we proposed to use the aerated concrete blocks with ceramic powder fibers to make sound insulation walls in an innovative structure of wedge absorber. The sound insulation walls can be constructed together with the roads and we believed the walls can perform well in noise reductions in city expressway.更多还原
