Finite-Element based multicriteria numerical optimization of geotechnical constructions at service limit state

基于有限元的岩土工程多准则数值优化（FEMNOG）的工作已经非常成功，最近的报告已经表明。对优化算法进行了修改，并将其应用于岩土工程任务;参见Grabe等人[5，6]，Pucker和Grabe [11，12]。由于经验表明，目标函数的经济可行性和施工时间很难以现实的方式获得，因此必须修改进一步的研究方案。为此，我们对目标函数进行了定制，以考虑地基沉降及其承载能力。研究计划在第5阶段进行了模型试验。实验将被用来验证数值结果定性。因此，将数值优化拓扑结构的模型实验与标准浅基础实验进行比较，以指出数值算法的潜力。在第6阶段，数值模拟和模型实验的结果用于开发新的创新基础结构。

The work on the finite element based multicriteria numerical optimization of geotechnical constructions (FEMNOG) has been very successful as the recent report has shown. The optimization algorithms were modified and applied to geotechnical tasks; see e.g. Grabe et al. [5, 6], Pucker and Grabe [11, 12]. The further research program had to be modified as the experience has shown that the objective function economical feasibility and construction time can hardly be captured in a realistic way. For the reason, the objective functions were customized in order to consider the settlements of foundations and their loading capacity.The research schedule is additionally extended with model experiments in phase 5. The experiments will be used to validate the numerical results qualitatively. Therefore, model experiments with numerically optimized topologies are compared to experiments with standard shallow foundations to point out the potential of the numerical algorithms.In Phase 6, the results of the numerical simulations and the model experiments are used to develop new innovative foundation structures.
