摘　　要：铁路闭塞分区的合理划分对于确保列车运行安全、提高铁路线路通过能力以及优化铁路运营效率具有重要意义。随着铁路运输需求的增加,如何有效划分闭塞分区,以提升铁路运输效率和安全性,成为亟待解决的关键问题。基于线路条件、列车制动距离、轨道电路长度等综合考虑闭塞分区划分影响因素,以缩短列车追踪间隔为目标,构建铁路闭塞分区划分优化模型,采用改进布谷鸟搜索算法进行求解。为增强算法的局部挖掘能力并加速其收敛过程,调整淘汰概率及步长控制量,改进布谷鸟搜索算法。仿真验证结果表明,基于改进布谷鸟搜索算法获得的闭塞分区布置方案有效缩短了列车追踪间隔时间,提高列车运行效率,同时体现了较快的求解速度和良好的计算精度,验证了该算法在铁路闭塞分区优化设计中的实用价值。The optimal setting of railway block sections is of great significance for ensuring the train operation safety,improve the line capacity and optimize the railway operation efficiency.With the increase of railway traffic,how to effectively set block sections to improve the efficiency and safety of railway transportation has become a critical question.Based on line conditions,train braking distance,track circuit length,and other factors influencing block section setting,the optimization model of railway block section is constructed and solved by improved cuckoo search algorithm aiming at reducing train interval.In order to enhance the local calcula‐tion ability of the algorithm and accelerate its convergence process,the elimination probability and step control quantity are adjusted,and the cuckoo search algorithm is improved.The simulation results show that the block section setting plan based on the improved cuckoo search algorithm can effectively reduce the train interval,improve the train running efficiency,and at the same time reflect the fast solution speed and good calculation accuracy,which verifies the practical value of the algorithm in the optimization design of railway block section setting.
