刘永琪(江苏农学院水利系)讨论: 论文在认定排水受阻的前提下,假定总应力不变,从质量守恒定律出发,写出液体非恒定渗流的连续性方程。引进各项系数之后,代入了各向同性的达西定律,最后将方程简化为: ΔH=X′ΔT,即归结为测压管水头变化值ΔH与温度变化值ΔT成线性比例关系,这个比例系数即为待求的X′。论文又从实测的测压管水头变化值及温度变化值找出一个系数就作为这个比例系数X′。以此来说明
Liu Yongqi (Department of Water Resources, Jiangsu Agricultural College) discusses: Under the premise that the drainage is obstructed, assuming that the total stress does not change, the paper proceeds from the law of conservation of mass and writes a continuous equation of liquid non-steady seepage. After the introduction of the coefficients, the isotropic Darcy’s law is substituted. Finally, the equation is simplified as: ΔH=X′ΔT, that is to say, it is linearly proportional to the variation of the pressure tube head ΔH and the temperature change ΔT. The coefficient is the required X’. The paper also finds a coefficient from the measured piezometric head change value and temperature change value as the proportional coefficient X′. To illustrate
