Collapse Upon Wetting
Eduardo Rojas
Abstract
This chapter presents the modeling of the phenomenon of collapse upon wetting using the effective stress equation established in Chapter 2 and the elastoplastic framework proposed in the previous chapter. Using the probabilistic porous-solid model, Bishop’s parameter χ can be obtained to determine the current effective stress. The proposed framework includes the hysteresis of the SWRC and to some extent the hydro-mechanical coupling of unsaturated soils. This model is able to reproduce some particularities of the phenomenon of collapse upon wetting that other models cannot simulate.
