摘要:本文对BIM技术在阜阳市大剧院复杂多曲形建筑施工中的应用难点进行了介绍。该工程是PPP形式。该工程结构新颖、姿态优美、造型独特，建筑外立面通过圆形斜柱、大跨度双曲面钢筋混凝土梁和异形网格状钢结构，共同组成三个玫瑰花瓣，彰显“七彩玫瑰”的设计理念。多曲结构图纸识图难，圆形斜柱、大跨度双曲面混凝土梁施工工艺远比普通钢筋混凝土施工工艺复杂，钢结构吊装体量大，形状复杂，传统钢筋混凝土及钢结构施工工艺无法满足本项目的施工质量及进度要求。本文通过BIM技术进行三维建模、三维模拟、数值提取、工况分析等，在波浪形混凝土环梁、大斜度混凝土柱、玫瑰花瓣形网格幕墙等方面进行研究，实现多曲组合结构精准建造，为后续类似项目提供借鉴。

Abstract: The PPP project of Fuyang Grand Theater has design innovation. The project is novelty in structure, elegant in posture, and uniqueness in form. The facade of the building is compositing of three rose petals through circular inclined columns, long-span hyperbolic reinforced concrete beams, and special-shaped grid steel structure, which is highlighting the design concept of "Seven Colored Roses". The diagrams of multi-curved structure is difficult to be read. The construction process of circular inclined column and long-span hyperboloid concrete beam is far more complex than that of ordinary reinforced concrete. The hoisting volume of steel structure is large and the form is complex. The traditional reinforced concrete and steel structure construction process can not meet the construction quality and progress requirements of the project. Through BIM Technology, three-dimensional modeling, three-dimensional simulation, numerical extraction, working condition analysis, and other technologies, the research is being carried out in the aspects of wavy concrete ring beam, highly inclined concrete column, and rose petal grid curtain wall for achieving the accurate construction of multi curved composite structure and for providing the references for those subsequent similar projects.
