| Zusammenfassung |
| Soil-atmosphere exchange leads to a moisture change in the soil. This can
cause major damage to engineering structures due to the soil expansion and
shrinkage. The soil-atmosphere exchange is related to several parameters,
in particular the soil characteristics and climate conditions. The presence of an engineering structure causes a variation of the hydraulic
profile in the soil, which can lead to heterogeneous soil movement and
consequently to structural damage. This paper presents a coupled numerical
model based on the consideration of both water flow in unsaturated soils and
soil-atmosphere exchange. After the validation of the model, the paper
presents its use for the analysis of the influence of the presence of
structures on moisture change induced under climatic conditions recorded
in a semi-arid region. Analysis shows that the presence of the structure
leads to important change in the moisture distribution, in particular in the
vicinity of the structure. |
