靖西天然气管道在陕西省富县洛河穿越处发生了断裂。通过实地勘察,对水流泥沙条件及设计方面存在的问题进行了分析。指出管道埋设位置不利以及设计配重和设计埋深低、是造成管道断裂的主要原因。建议在管道穿越多沙河流时,一定要按高含沙水流特点进行设计埋深的研究和计算。
Jingxi natural gas pipeline ruptured at Luohe crossing in Fuxian County, Shaanxi Province. Through field investigation, the problems of water and sediment condition and design are analyzed. It is pointed out that the unfavorable location of pipeline and the low design depth of the design counterweight are the main reasons for pipeline fracture. It is suggested that when the pipeline crosses the Dousha River, it is necessary to study and calculate the design depth according to the characteristics of high silt water flow.
