摘要:: 1998年嫩江洪水淹没了大庆输油公司的 32.1km双线管道,通过现场调查掌握了最高水位期和冬季冰冻期的淹没范围?进行冰冻期管堤冻结?冻胀和温度场的计算分析后可以断定管道不会冻胀发生破坏,但由于热量散失严重要增加燃油消耗,为此提出在增加管堤敷土的同时,应开展管堤保护技术的研究工作?
The Nenjiang river flood inundated area of 31.2km double-line-pipeline of the Daqing oil transmission company in 1998.By investigation in field the highest water level period and the flooding area of frozen period are known. After calculation frost of pipe dike,frost expansion and temperature field during the frozen period this paper states that the pipeline can not be broken down.However more fuel consumption is needed because of thermal losses.Therefore the research work of pipe protection technology should be carried out while increasing of pipe dike soil coverage is raqined.
