摘要： 建筑结构基础设计直接关系整个建筑的主体安全,是建筑结构设计的重要内容。现阶段，设计人员通过地质勘察报告，掌握地质水文、自然环境等情况，根据设计经验，综合考虑与上部结构的关系，进行沉降量、地基应力等计算，从而确定基础选型。BIM正向设计的理念融入到基础结构的设计中，通过建立Revit地质模型，全面了解持力层的分布情况，确定基础埋深和尺寸，结合设计计算，进行方案比选，可极大程度发挥BIM技术的可视化和模拟性，让基础选型的过程更加直观，方案的提出更加高效。

Abstract: Foundation type selection is an important content of the building structure design that is related to the overall safety of the building structure. Currently, the selection of foundation type is made based on the geological and hydrogeological conditions, topographical conditions, superstructure information and experience of the structural engineer and throughout the settlement and bearing resistance estimations. This paper combines the concept of the forward design in the Boulding Information Model (BIM) in the foundation type selection design and subsurface conditions are represented by the Revit geological model. So that the stratigraphy of soil and rocks can be visualized. The foundation embedment and dimensions are presented visually in the BIM system. The advantage of using BIM system is that the selection of foundation system can be accelerated throughout the visualization.  

Key words: foundation structure, geological model, foundation comparisons, forward design, building information model
