Towards the Holistic Simulation of Geotechnical Foundation Processes Using Vibro-Injection Piles
Abstract In civil engineering, the installation of a reliable foundation is essential for the stability of the emerging structure. Thus, already during the foundation process, a comprehensive survey of the mutual interactions between the preliminary established construction pit and the surrounding soil is indispensable, especially when building in the existing context. Addressing the simulation of geotechnical foundation processes using vibro-injection piles, complex initial-boundary-value problems are necessary. In particular, the numerical model is composed of several mutual interacting parts, such as retaining walls, anchors and vibro-injection piles, all interacting with the surrounding soil. Additionally, a fine mesh is required in order to adequately resolve local effects such as shear bands. However, when such complex simulations are inevitable, explicit time-integration schemes are advantageous over implicit schemes. In this regard, the present contribution addresses the development and application of a numerical soil model based on the Theory of Porous Media, which is suitable for simulations exploiting the explicit time-integration schemes of Abaqus/Explicit. The underlying numerical soil model is investigated in terms of accuracy and parallel efficiency.
