摘要：
The paper deals with a numeric model for coupled solid-fluid FE analyses of geotechnical problems involving partially saturated soils. The Barcelona Basic Model serves as a constitutive model for the soil skeleton. Different stress update algorithms are compared for this model regarding robustness, accuracy, and efficiency. The application of the numerical model is demonstrated by numerical simulations of the impoundment of an earth dam and of the injection of compressed air into water saturated soil.
