摘要浩吉铁路作为“北煤南运”新通道,自建成运营以来运量增长较快。浩吉铁路集疏运系统以襄州北站为分界,襄州北站以北的集运系统能力及增量潜力充足,而襄州北站以南的疏运系统能力存在瓶颈,主要受到襄州北至坪田段区间通过能力及襄州北站万吨列车组合分解能力的共同制约。在综合考虑浩吉铁路货运增量目标、运输组织效率的提高,点线能力协调的基础上,提出浩吉铁路襄州北至坪田段采用提高牵引质量至10 000 t、对欧庙、掇刀、江陵、松木桥及坪田5个车站实施开行万吨列车改造、增开万吨直达列车的扩能方案。通过万吨车站扩能改造,襄州北站万吨列车组合分解作业量减少40%,襄州北—坪田段运输能力提升10%以上,浩吉铁路全线点线能力趋于平衡,为实现全线规划运量目标2.4亿t奠定基础。 As a new corridor of transporting coal from north to south,the traffic volume of Haoji Railway has increased rapidly since it was built and put into operation.The collection and distribution system of Haoji Railway is divided at Xiangzhou North Sta‐tion.The capacity and increase potential of the collection and distribution system north of Xiangzhou North Station are sufficient,while the capacity of the distribution system south of Xiangzhou North Station has bottlenecks,which are mainly restricted by the passing capacity of the section from Xiangzhou North to Pingtian and the combined decoupling capacity of 10000 t trains in Xiang‐zhou North Station.Comprehensively considering the freight increase target,improvement of transportation organization efficiency and coordination of point-line capacity of Haoji Railway,this paper puts forward the capacity expansion plan of improving traction quality to 10000 t in Xiangzhou North-Pingtian section of Haoji Railway,implementing the transformation of 10000 t trains and adding 10000 t direct trains to five stations,namely Oumiao,Duodao,Jiangling,Songmuqiao and Pingtian.Through the expansion and reconstruction of the 10000 t station,the combined decoupling operation volume of 10000 t trains in Xiangzhou North Station is reduced by 40%,the transportation capacity of Xiangzhou North-Pingtian section is increased by more than 10%,and the point-line capacity of Haoji Railway tends to be balanced,laying a foundation for realizing the transportation volume target of 240 million tons.
