摘要

本文的目的是提出建模和分析步骤，以评估和设计一个储存库结构，这将被用于长期储存低放射性和中放射性废物。它的最初设计始于90年代初，但当时还没有完成。随着近年来抗震要求的显著提高，需要对结构进行新的设计。同时考虑了土-结构相互作用的影响，实施了两个分析实例。在第一种情况下，土壤-结构系统被考虑在一个单一的模型中，实现子结构方法。在第二种情况下，土-结构相互作用效应是通过两步建模程序确定的，首先产生适当的土弹簧，然后连续地将它们引入结构的数值模型。这两个独立的分析过程是必需的，以便不仅对存储库结构本身，而且对各个组件实现一个集成的评估和设计过程。

Seismic soil-structure – interaction analysis of a radioactive waste repository considering on site measurements and subsoil improvement

Aim of this paper is to present the modelling and analysis steps for the evaluation and design of a repository structure, which will be used as a long-term storage for low and intermediate radioactive waste. Its initial design began in the early 90ies but it was not concluded at that time. As the seismic requirements increased significantly over the past years, the new design of the construction is required. Two analysis cases are implemented considering both the soil – structure interaction effects. In the first case, the soil –structure system is considered in one single model implementing the substructuring method. In the second case the soil – structure interaction effects are determined in a two-step modelling procedure by generating at first appropriate soil springs and introducing them continuously to the numerical model of the structure. These two separate analysis procedures are required in order to achieve an integrated evaluation and design process not only of the repository structure itself but also for the various components.
