| Abstract: | Through the actual measurement of the operating noise of the elevated section of Chengdu Metro Line 18,the noise source intensity and horizontal propagation characteristics are analyzed.According to the prediction mode in Environmental Impact Assessment Technical Guidelines for Urban Rail Transit(HJ 453—2018),A-weighted sound level at each horizontal measuring point is predicted,and the prediction results are compared with the measurement results.The results show that the degree of prediction accuracy is high and can be used for noise prediction for the elevated section of the newly-built urban express line. |
