Road noise visualization evaluation method based on BIM and GIS

Abstract

The invention provides a road noise visualization evaluation method based on BIM and GIS, and relates to the field of environmental protection engineering. The road noise visualization evaluation method based on BIM and GIS comprises the following steps: S1, detecting a road noise propagation rule; S2, establishing a corresponding noise weakening model; S3, establishing a space model; S4, performing data input; S5, performing a contrast experiment; S6, correcting the simulation experiment; S7, performing road noise simulation; and S8, watching and analyzing the data. By modeling a road project and the surrounding environment, the noise distribution on the whole road line is intuitively represented in a simulation form, and a noise topographic map of the road project is constructed, so that the noise influence is visualized, the working hours can be greatly shortened, the heavy calculation work of environmental assessment workers is reduced, the working efficiency of environmental assessment workers is improved, and the accuracy and scientificity of environmental assessment results are improved, so that more accurate noise influence prevention and control are realized.

Description

technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to a BIM and GIS-based visual evaluation method for road noise. Background technique [0002] With the growth of the economy and the development of the transportation industry, the traffic noise caused by the operation of private cars, high-speed railways, airplanes, etc. has become a major problem that plagues urban and rural residents, and its harm has been recognized. High-decibel, long-term traffic noise can damage people's hearing, reduce memory, and increase the risk of endocrine disorders and cardiovascular diseases. The short-term traffic noise will also interfere with normal rest, causing people's irritability, fatigue, emotional abnormalities and so on. According to the 2020 Environmental Noise Pollution Prevention and Control Report, the areas on both sides of the main traffic line (category 4a functional areas) have the lowest night-time com...
