| 摘 要： | 在老旧城区内采用定向钻进敷设地下管线，常常需要从已有的各类地下建（构）筑物或管线下方穿过，方案设计时就应考虑新建管道与之安全距离的取值问题。以厦门市某110 kV电力电缆的定向钻进工程的实际需求为出发点，在对国内现有规程规范及工程实例调查的基础上，对电力电缆保护管定向钻进敷设安全距离取值的影响因素进行分析，优化工程定向钻进敷设方案，指导该工程的建设，并为类似工程建设提供参考。

| Abstract: | Being restricted by the environment and according to the urban planning, some HV cables have to be laid under the existing buildings or pipelines, the values taking for safety distance should be calculated in the trajectory design. In this paper, a case of directional drilling project is discussed, which is 110kV HV transmission cable line in Xiamen. According to the existing technical codes in China and based on the engineering cases investigation, the analysis was made on the influencing factors on the safety distance value taking for electric power cable protection pipe laying to optimize the pipe laying trajectory. Xiamen 110kV HV cable protective pipes have been laid successfully under the ground, which can provide references for similar construction. |
