| 摘要： | The construction of line infrastructure in Sweden often involves construction of superstructures such as embankments, bridge footings, excavation and/or cut slopes on very soft soils. Each of these construction activities results in a very different and complex soil response. Especially in urban areas, this requires advanced numerical analysis when the serviceability limit state (deformations, life-time maintenance costs) is considered. A major problem is that the soil models that are available in commercial FE codes have never been comprehensively validated against real soft soil data and that the model parameter determination is far from trivial. The latter is even more complicated for typical Swedish site investigation data which is not ideal. The proposed project is positioned very close to engineering practice as it aims to develop best practice guidelines for model selection and systematic parameter determination for the application of standard and advanced constitutive models for soft soils in Swedish conditions by establishing a suitable model parameter determination protocol and assessing the merits of the standard and advanced models for modelling soft soils in infrastructure applications. The project will contribute to improved analyses of deformations around embankments, cut slopes and deep excavations, and in general, it will improve the ability of Swedish geotechnical engineers to use FE analyses for soft clays. |
