根据近年来一系列的研究証明,水在粘性土中的渗透不完全符合于达西(Darcy)定律,而在某种特定条件下有其特殊的渗透規律。1930年苏联布寿列夫斯基首先注意到粘土中的渗透水在小于某一定值的水力此降下不发生渗透,并称这一此降为开始此降。以后有許多学者继续对此間题进行了研究,并有了进一步的发展。本文主要是利用不同性质的液体在細孔介貭中的渗透規律,来比拟水在粘土中的渗透,然后与一系列的試驗賽料进行此較,从而找出粘土的渗透規律。
According to a series of studies in recent years, the penetration of water in cohesive soils does not fully comply with Darcy’s law, but it has its own special permeability under certain conditions. In 1930 the Soviet Union Buscherevsky first noticed that the permeated water in the clay did not permeate below a fixed value of hydraulic force, and said this was reduced to the beginning of this drop. In the future, many scholars have continued to study this topic and have further developed. This paper mainly uses the permeability of liquids with different properties in the porous media to compare the penetration of water in the clay, and then compared with a series of test competitions to find out the permeability of the clay.
