客运专线环境影响特性探讨

客运专线主体结构以桥梁为主,具有不同于普通铁路的工程建设特性,从而导致不同的环境影响特性。如生态环境影响特点为客运专线桥梁工程桩基施工弃土量、泥浆处置量大,制梁场等临时工程占地多;声环境影响具有声源位置高、声源成分复杂的特点,随着列车运行速度增加,空气动力噪声和集电系统噪声显著增加;电磁环境影响特点,高架线路对电磁的遮挡、反射影响不容忽视,电磁辐射影响与车速呈正比。

Discussion of Environment Impacts Characters of the High Speed Railway

Different from the ordinary railway,the high speed railway which is main consistent of bridges, will lead to some different characters of environmental impact. The characters of the high speed railway environmental impacts include large amount of spoil and mud from the bridges, land use by the temporary engineering about ecological environment, and complex sound sources with high position and the speed of the train about acoustic environment and the reflection radiation which increases proportioned with the train speed. This article analyzes these environmental effects of the high speed railway and provides the mitigate measures to reduce the environment impacts.
