摘　　要：为落实发展绿色物流的要求,提升铁路运输能力,需要对既有沙午线(沙河—午汲)进行扩能改造。在阐述既有沙午线现状的基础上,结合配套扩能改造方案,对配套扩能改造方案进行分段研究,按照内燃牵引方案I和电力牵引方案II 2个方案对南营井—午汲段扩能改造方案进行技术经济比选,推荐采用方案II-3(电力双机牵引5 000 t);按照方案I(内燃双机牵引4 000 t)和方案II(电力双机牵引4 000 t)2个方案对南营井—沙河段扩能改造方案进行技术经济比选,推荐采用方案II(电力双机牵引4 000 t)。通过方案比选为沙午线扩能改造提供经济合理建设方案。Capacity expansion of the existing Shahe-Wuji line is required to develop green logistics. This paper, with an elaboration on the current railway line, has analyzes the capacity expansion plan that covers different sections of the line. After comparing the cost-efficiency between the diesel locomotive and the electric train for the section from Nanyingjing to Wuji, this paper recommendeds plan II-3 of electric locomotives in double-heading with the tractive power of 5,000 tons. For the section from Nanyingjing to Shahe, the paper also compares the two options which are diesel locomotives in double-heading with the power of 4,000 tons and electric double-heading of the same power. The later is recommended due to its higher cost-efficiency. These findings are expected to contribute to a final plan for the expansion of the Shahe-Wuji railway.
