摘要:
综合考虑虹吸式屋面雨水排水系统在不同设计阶段的内容及特点，提出一种针对设计全过程的智能设计框架，并基于Grasshopper平台开发了相应智能设计工具。该工具运用参数化设计技术与计算流体力学（CFD）仿真模拟技术，以建筑屋面模型为基础，实现了径流分析、水力计算、方案生成、智能优化、仿真校核等功能，不仅极大程度提高了虹吸排水系统的设计效率，而且确保了方案的精确性与最优性，同时保障了方案在多种真实工况下的安全性与可靠性。详细阐述了工具内各模块的关键技术及实现方法，并通过工程实例验证了工具的可行性与高效性。
Abstract:
Considering the content and characteristics of siphonic roof drainage system in different design stages, this paper proposed an intelligent design framework for the whole design process, and developed a corresponding intelligent design tool based on Grasshopper platform. Based on building roof model, the tool realized functions such as runoff analysis, hydraulic calculation, scheme generation, intelligent optimization and simulation check, which greatly improved the design efficiency of siphonic roof drainage system and ensured the accuracy and optimality of the scheme by using parametric design technology and computational fluid dynamics (CFD) simulation technology. In addition, it guaranteed the safety and reliability of the scheme under various real working conditions. The key technologies and implementation methods of each module in the tool were described in detail, and the feasibility and efficiency of the tool were verified by an engineering example.
