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

如最近的报告所示，基于有限元的多准则岩土结构数值优化(FEMNOG)的工作已经非常成功。优化算法被修改并应用于岩土工程任务；例如，见Grabe等人。[5，6]，Pucker和Grabe[11，12]。进一步的研究计划不得不修改，因为经验表明，目标函数、经济可行性和施工时间很难以现实的方式捕捉到。为此，定制了目标函数，以考虑地基的沉降及其承载能力，并在第五阶段增加了模型试验。试验将用于定性地验证数值结果。因此，将数值优化拓扑的模型试验与标准浅基础的试验进行了比较，以指出数值算法的潜力。在第六阶段，利用数值模拟和模型试验的结果来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.
