摘　　要：国内多地冬天雪季频繁,及时对道岔进行除雪非常重要,安装道岔融雪装置可以有效清除道岔关键部位的积雪,提高铁路运输效率。但是道岔融雪装置经过多年运用,也暴露出较多缺点。针对目前道岔融雪装置用电负荷量巨大、工程造价居高不下以及国内下雪范围南移等问题,选取不同区域大、中、小型铁路车站为例,研究道岔融雪装置工程设计方案,优化道岔融雪装置设计标准,对于铁路道岔融雪装置工程设计有重要的指导意义,可为完善相关标准、规范提供技术支持。Because it snows frequently in winter in many places in China, it is very important to remove the snow from the turnouts in time. The installation of snow melting devices for turnouts can effectively remove the snow from the key parts of the turnouts, and improve the efficiency of railway transportation. However, after years of use, more and more shortcomings of such devices have been exposed. In this paper, in order to address the current problems, including the vast electricity load of such devices, the high engineering costs and the fact that it starts to snow in more areas in southern China, large, medium and small railway stations in different regions are chosen as examples to study the engineering design schemes and to optimize the design standards of such devices. This paper has important significance for guiding engineering design in this field, and provides technical support for improving related standards and specifications.
