建筑环境与能源应用工程专业城市燃气工程方向管网规划类毕业设计受水力计算手段限制，存在管网方案布置不尽合理、水力计算效率低、工况分析不全面等问题，将虚拟仿真模拟软件作为新的教学手段引入毕业设计，可明显改善这一状况。文章分析了水力计算手段对管网规划类设计的影响，对适用于毕业设计的虚拟仿真模拟软件进行了介绍，将在毕业设计中应用虚拟仿真软件作为辅助设计手段前后的设计效果，从软件使用前后规划方案的变化、水力计算能力、事故工况分析能力、新题目的出现与完成四个方面进行了对比分析，结果显示，虚拟仿真软件可明显提高毕业设计质量。

Building environment and energy application engineering city gas engineering direction pipeline network planning graduation design is limited by hydraulic calculation means, and there are problems such as unreasonable pipeline network scheme, low-efficiency hydraulic calculation, and incomprehensive working condition analysis, etc. The introduction of virtual simulation software as a new teaching method can significantly improve this situation. This paper analyzes the influence of hydraulic calculation methods on the design of pipeline network planning, and introduces the virtual simulation software suitable for graduation design. The changes of planning schemes, hydraulic calculation ability, analysis ability of accident conditions, and emergence and completion of new problems after using virtual simulation software as auxiliary design method in graduation design are compared and analyzed. Conclusion that virtual simulation software can significantly improve the quality of graduation design is obtained.
