城市隧道设备系统节能环保的分析和思考

Analysis and Thinking about Energy Conservation and Environmental Protection of Urban Tunnel Facilities System

介绍了城市隧道节能、环保措施。主要有:变电所选址需接近负荷中心,减少供电距离;隧道照明要选用高光效、长寿命、高质量的绿色光源和高效灯具,充分利用自然光,选取合适的照明控制方式;通风设备采用纵向通风和控制风机开启数量,以及噪声控制和废气排放处理;对排水系统通过合理的横截沟设计来节能。最后指出:由于对节能概念理解差异、投资渠道尚待完善和项目风险大等因素,所以急需政府政策推动和支持。

This paper was mainly about energy conservation and environmental protection of ubran tunnel. Several measures were mentioned including electric power substation being near load centre, shortening power distance, choosing green light source, efficient lighting luminaires and controlling method, taking advantage of natural daylight, etc. Otherwise, ventilation equipment should be designed with longitudinal ventilation and the quantity of the fans should be controlled. Meanwhile, noise control, toxic emission treatment and reasonable drainage system design also would be useful for energy conservation. Finally, the author pointed out that the government should be the key supporter for these measures because of understanding difference, incomplete investment channel and high risk.
