WebAug 23, 2024 · The permeability of the foundation at dam sites is usually explored by means of water pressure tests (WPT), also called Lugeon-tests. This part of the paper focuses on the most important topics of the execution, evaluation, interpretation and application of the results. Download chapter PDF. The permeability of the foundation at … WebNov 19, 2024 · There are two different permeability models for rocks: the capillary model of pores and the fracture model. For granular rocks the Kozeny–Carman equation is applicable, in which hydraulic radius and degree of tortuosity are involved. The effect of pore pressure can be described using the effective pressure transfer coefficient.
