在概念上渗透试验是简单的——将水注入孔洞,并测定渗吸的快慢。但问题却很复杂。1.试验是经验性的且非规范化;2.饱和—非饱和流理论表明,圆柱形孔洞中水面下降速率(即渗透速率)除依赖于土壤导水率外,还有许多因素;3.在流体移动特性方
The concept of penetration test is simple—inject water into the hole and measure the rate of infiltration. But the problem is very complicated. 1. The experiment is empirical and non-canonical; 2. The theory of saturated-unsaturated flow shows that the rate of water surface decline (ie, the permeation rate) in the cylindrical hole is dependent on the hydraulic conductivity of the soil; there are many factors; Fluid movement characteristics
