现代有轨电车无砟轨道的排水设计直接影响有轨电车的行车安全和设备设施的有效性，它与普通铁路排水设计存在差别，与市政道路排水系统既相似又有不同之处。结合工程设计经验，从有轨电车排水系统的组成、设计重现期、雨水量计算、排水沟管等方面，对现代有轨电车排水设计进行了分析与讨论。

Drainage design of modern tram affects the tram traffic safety and the efficiency of equipment and facilities directly. It is different from drainage design of common train. It is somewhat similar to and also somewhat different from municipal road drainage systems. By referring to the engineering experience, the drainage design of modern trams were analyzed and discussed from aspects of the composition of the drainage system, design storm frequency, rainfall calculation, drainage ditch and pipe.
