摘　　要：基于GIS的声屏障路段三维评价区域交通噪声环评可视化目前还未能实现。对此提出自适应变层厚切片算法、基于道路及声屏障几何参数的各分层内声影区与声照区笛卡尔网格生成算法。对于声屏障路段,解决了现有国家标准仅能人工查表进行离散点计算的问题。采用分层等值线方法实现了三维可视化显示。通过高速公路声屏障路段的实例,验证了算法的准确性。实际应用表明,该系统能够准确、快速、直观地反映交通噪声对道路周边环境的影响及声屏障的降噪效果,在环评及城市规划中具有很好的应用前景。The GIS-based 3D evaluation area traffic noise EIA visualization of noise barrier road section has not achieved.In view of this,this paper proposes the adaptive layered cutting algorithm and the Cartesian grids generation algorithm of sound shadow zone and sound direct zone based on the geometric parameters of road and noise barrier.For the road section with sound barrier,it solved the problem that the existing national standard could only check the table manually to calculate the discrete points.A contour algorithm within the slicing plane was used to realize 3D visualization.The accuracy of proposed method was verified by the example of highway noise barrier section.The practical application shows that the system can accurately,quickly and intuitively reflect the impact of traffic noise on the surrounding environment of the road and the noise reduction effect of the noise barrier,and it has a good application prospect in the EIA and urban planning.
