지하철의 기하구조와 운영요소가 소음에 미치는 영향에 관한 연구 = The Effect of Subway Geometric and Operational Elements on Noise for 5th Subway Line in the Seoul City

다국어 초록 (Multilingual Abstract)

The subway is a necessary public transportation in big cities, which many citizens are using now. However, the demands for subway inner circumstance by citizens are growing recently. Among them, the noise problem is the hot issue to be solved. Based on noise level data in Subway Line 5 in Seoul, relations Between noise level and other factors including geometry design and operational factors are analyzed. So this study analyzes the noise problem in subway with the following results. First, as a result of relation analysis, the noise degree is deeply related to the subway speed, the tunnel configuration, size, and the rail type. Second, the factor analysis shows that various independent variables are grouped with tunnel type and rail type. Last, the model establishment for noise factor found that the subway speed, tunnel, and rail have biggest relations with the noise.
