摘要
提出了一种新的求参方法──“同定参数法”，按该方法求原状土样参数的原理设计制作了求参装置，在求参过程中，通过迭代法修正水分特征曲线，求得原状土样非饱和水力传导度。
A new experiment method for determining parameters of soil water movement is put forward, which is that two parameters are determined in the same one experiment According to the principle of determining undisturbed soil sample parameters, a new device is designed and introduced. Through successive correction of the assumed soil water characteristic curve by iteration method, unsaturated hydraulic conductivity of the undisturbed soil sample is obtained. At the same time, the soil water characteristic of curve of the soil sample is also obtained.
