Both planning and design phase of large infrastructural project require analysis, modelling, visualization, and numerical analysis. To perform these tasks, different tools such as Building Information Modelling (BIM) and numerical analysis software are commonly employed. However, in current tunnel engineering practice, there are no systematic solutions for the exchange between design and analysis models, and these tasks usually involve manual and error-prone model generation, setup and update. In this paper, focussing on tunnelling engineering, we demonstrate a systematic and versatile approach to efficiently generate a tunnel design and analyse the lining in different practical scenarios. To this end, a BIM-based approach is developed, which connects a user-friendly industry-standard BIM software with effective simulation tools for high-performance computing. A fully automatized design-through-analysis workflow solution for segmented tunnel lining is developed based on a fully parametric design model and an isogeometric analysis software, connected through an interface implemented with a Revit plugin. The IGA-Revit interface implements a reconstruction algorithm based on sweeping teachnique to construct trivariate NURBS lining segment geometry, which avoids the burden to deal with trimmed geometries.

大型基础设施项目的规划和设计阶段都需要分析，建模，可视化和数值分析。为了执行这些任务，通常采用不同的工具，例如建筑信息模型（BIM）和数值分析软件。但是，在当前的隧道工程实践中，没有用于设计和分析模型之间交换的系统解决方案，这些任务通常涉及手动和易于出错的模型生成，设置和更新。在本文中，我们着重于隧道工程，展示了一种系统化的通用方法，可有效地生成隧道设计并分析不同实际场景中的衬砌。为此，开发了一种基于BIM的方法，它将用户友好的行业标准BIM软件与有效的仿真工具相连接，以实现高性能计算。基于完全参数化的设计模型和等几何分析软件，开发了用于分段隧道衬砌的全自动分析设计工作流程解决方案，该软件通过Revit插件实现的接口进行连接。IGA-Revit接口实现了一种基于清扫技术的重建算法，以构造三元NURBS衬砌管段几何形状，从而避免了处理修剪后的几何形状的负担。
