摘　　要：综合管沟中热力管线由于温度较高通常独立分舱敷设,以免影响其他管线正常运行,电力线缆对温度较为敏感,高温状态下会加速电缆绝缘层老化增加事故风险。由于场地条件局限或造价成本限制,综合管沟有时采用单舱形式,在这种情况下热力管线产生的热量是否会影响电力线缆的运行和安全性能值得讨论。以某综合管沟项目为例,通过散热量计算管沟温度,分析热力管线对供电电缆的影响,为实际工程设计提供一些参考。Due to the high temperature,the heating pipelines in the integrated trench are usually laid in separate compartment so as not to affect the normal operation of other pipelines.The power cables are sensitive to temperature,and the aging of the insulation layer of the cables will be accelerated under high temperature condition and the risk of accidents will be increased.Due to the limited site conditions or cost constraints,the integrated trench sometimes adopts the form of single compartment.In this case,whether the heat generated by the heating pipeline will affect the operation and safety performance of the power cable is worth discussing.Taking a comprehensive trench project as an example,the temperature of the trench is calculated through heat dissipation,and the influence of the thermal pipeline on the power supply cable is analyzed,which provides some references for the practical engineering design.
