提高运输能力是我国铁路当务之急。增大货车轴重、实现重载运输是解决运能不足的最有效的措施之一。本文结合我国实际情况对国外轴重研究结果进行了分析对比,得出轴重与钢轨重量、轮径大小的合理匹配的具体数据。最后提出了我国近期发展轴重23吨的货车和远期把轴重提高到25吨的建议。
Improving transportation capacity is a top priority for China’s railways. Increasing the axle load of trucks and realizing heavy-haul transport are one of the most effective measures to solve the problem of insufficient transport capacity. Based on the actual situation in our country, the results of the research on the axle load abroad are analyzed and contrasted, and the specific data about the reasonable matching between axle load, rail weight and wheel diameter are obtained. Finally, the author put forward the suggestion that China’s recent development of a 23-ton truck and a long-term increase of axle load to 25 tons.
