倾斜管道水力坡度的研究

Study on hydraulic gradient of inclined pipeline

针对国内倾斜管道水力坡度的研究较少,在工程中,管道输送不可避免地要穿过地势起伏较大的地区的情况,研究了倾斜向下管路中的水力坡度损失。在前人的研究基础上,推导出了向下倾斜管道沉降性浆体的水力坡度计算公式。其次,还利用相关数据对推导出的公式进行了检验,比较了计算值与实测值的差异,结果两者误差很小。最后分析了推导出的公式存在的不足,提出了下一步要做的工作。

Considering the fact that research on inclined pipeline transportation is much less, while in actual project ,pipeline transportation is inevitable to cross the areas with much rise and fall, we study the hydraulic gradient in the downward inclined pipeline .On the basis of forefathers' research,we derive and publish hydraulic gradient of settling slurry in downward-inclined-pipeline. In addition, related datum are used to verify the formula which has been deprived,and after comparing the difference between calculating value and conveying value,we found little difference between them. Finally we analyze the defect of formula deprived and put forward the work to do about the formula.
