“…However, contrary to what it was made in [14], where it was necessary to adjust the value of the elastic parameters, the elasto-plastic parameters used to obtain the results of the Fig. 9 were direclty the ones provided by [33]. In other words, no calibration of model parameter was realized.…”

“…We assume that the balls remain spherical except for the flat portion of the contact. The values of a and  are given by equations (6) to (8) of the elastic Hertz contact between the two spheres. The value of the normal force F N to the contact plane is given by equation (9) which takes into account le value of the suction and the value of the surface tension T c The contact between the particles and the water has a wetting angle of  c which varies in case of drainage or humidification (Gras, 2011).…”

Abstract. Modelling the relation between the degree of saturation and the suction (ie retention curve) is an important challenge for geotechnical engineering. It has a huge influence on the behavior of large soil constructions as levees, embankments, road earthworks. We present here a theoretical model of retention curve which considers physical relations of unsaturated soils. With this approach, there is no need to assume particular shapes of the retention curves, which are a consequence of the physical assumptions. The present study is focused on a theoretical model based on elastic spherical particle arrangement. As a first step a uniform model is presented with a single diameter of soil particle. A second step extends the use of the model to graded soils. The model uses only 5 physical parameters. It is compared with the experimental retention curve of two different samples of glass uniform particles and two different graded soils, a graded glass sample and the Livet-Gavet loam. It shows its ability to model the experimental curves and a better agreement than the former theory of Brooks and Corey (1966). This current publication is funded by the French National Project « Terredurable» (ANR 2011),.
