粤海铁路轮渡货物运输稳定性试验研究

Stability Test of Guangdong-Hainan Railway Ferry Freight Transportation

粤海铁路轮渡作为连接海南与大陆铁路的通道,推动了海南的经济发展和自贸港建设。在铁路轮渡运输过程中,风浪造成的船体摇摆对列车装载货物的稳定性产生不利影响,通过阐述粤海铁路轮渡货物运输概况,分析铁路轮渡运输稳定性影响因素,构建铁路轮渡货物运输稳定性模型,测试粤海铁路轮渡货物运输在6~8级风的临界封港海况下航运时,铁路列车甲板不同位置处加速度、摇摆角变化情况,以及该海况下航运时铁路货车所装货物的加速度和货物状态,研究相关铁路货物装载加固定型方案在粤海铁路轮渡临界封港海况下航运时的安全稳定性,为充分释放粤海铁路轮渡的运输能力提供技术依据。

Guangdong-Hainan railway ferry,as a channel connecting Hainan Province with the mainland,promotes Hainan's economic development and the construction of a free trade zone.In the process of railway ferry,the ship swaying caused by wind and waves will have adverse impact on the stability of the cargo loaded on the train.Based on the general situation of Guangdong-Hainan railway ferry freight transportation,this paper analyzes the factors influencing the stability of railway ferry transportation,and constructs the stability model of railway ferry freight transportation.The acceleration and swing angle of different positions of railway train deck during the transportation of cargo by Guangdong-Hainan railway ferry under the critical closure sea condition of gale 6 to 8 are tested,as well as the acceleration and cargo status of the goods loaded on the railway freight cars under the sea conditions of the critical closure of the sea state of the Guangdong-Hainan railway ferry safety and stability of shipping,which provides technical basis for fully releasing the transport capacity of Guangdong-Hainan railway ferry.
