修正的Kovacs（MK）模型是从土壤基本性质出发估算土壤水分特征曲线的一个通用而实用的工具。然而，MK模型还没有被引入到许多代码或分析解决方案;大多数应用程序，而不是使用布鲁克斯和科里（BC）和/或货车范希滕（vG）公式来表达WRC。本文提出了一种将MK模型参数直接转换为桑迪和粉质材料的BC和vG方程参数的方法。建议的方程开发使用的数据从15种类型的桑迪和14个低塑性粉土和验证使用16个其他土壤。本文给出的结果表明如何BC和vG方程参数可以成功地预测MK模型参数。转换过程提供了一种实用的方法，从土壤的基本岩土性质来估计WRC，并使用三种不同的数学公式来表示该曲线：MK，vG和BC。这些表达…
AbstractThe modified Kovacs (MK) model is a versatile and practical tool to estimate the water retention curve (WRC) of soils from their basic properties. However, the MK model has not yet been introduced in many codes or analytical solutions; most applications rather use the Brooks and Corey (BC) and/or van Genuchten (vG) formulations to express the WRC. The authors propose in this paper a direct conversion of the MK model parameters to the BC and vG equations parameters for sandy and silty materials. The proposed equations were developed using data from 15 types of sandy soils and 14 low-plasticity silts and validated using 16 other soils. The results presented in this paper indicate how the BC and vG equations parameters can be successfully predicted from the MK model parameters. The conversion procedure provides a practical means to estimate the WRC from the basic geotechnical properties of soils and to express this curve using three different mathematical formulations: MK, vG, and BC. These expressio...
