摘要
长输管道系统的可靠性是由许多要素共同决定的,管道压重效果便是其中之一。总结得出了决定管道压重效果的两个核心要素——抗飘浮计算和压重形式。通过对两种抗飘浮计算理论的对比分析,得出了"抗飘浮不应全部按净水压力计算,在特殊情况下应采用动水压力计算"的结论。通过对不同压重形式优缺点进行比较,得出了"一般地层宜采用土工平衡压袋稳管,坚硬岩层宜采用混凝土连续浇注稳管"的结论。
The reliability of the long- distance pipeline system is determined by many factors,the weight loading effect is one of them.In this paper,it is concluded that the weight loading effect is decided by two core elements- floating resistance calculation and weight loading form.Through the contrastive analysis on the two kinds of floating resistance calculation theory,it is further concluded that ＂Pipe floating resistance should not be calculated by hydrostatic pressure only,hydrodynamic pressure calculation should be adopted in special circumstances＂.Through the comparisive study on the advantages and disadvantages of different weight loading forms,the conclusion is also obtained that ＂Earth balanced weight bags are fit for general formation;but continuous concrete casting is fit for hard formation＂
