摘　　要：结构设计合规性检查是确保建筑信息模型(BIM)符合设计要求的有效手段,提高规范检查的自动化程度与准确度对于实现结构全寿命周期管理具有重要意义。基于自动化规则检查理论,采用可视化编程与C#编程结合开发的方式,提出了基于BIM水工结构设计合规性检查框架。基于Civil3D创建水工结构初级模型,并进行相应属性拓展。通过Dynamo对模型细化并提取模型信息以创建模型信息库。对相关规范进行解析,并依据标准对构件分类编码,储存在SQL Server数据库中以创建规则知识库。最后将规则知识库与模型信息库连接交互,从而实现水工BIM模型合规性检查。该方法极大地提高了基于BIM水工结构设计合规性检查效率和准确度,降低了开发难度,为促进水工结构设计合规性检查奠定了基础。Compliance inspection of structural design is an effective means to ensure that the building information model meets the requirements of the current design specifications.It is of great significance to realize the structural life-cycle management by improving the automation and accuracy of the specification inspection.Based on the theory of automatic rule checking and combining visual programming with C#programming,the paper proposes a design compliance checking framework depended on the BIM model of hydraulic structures as the inspection object.Firstly,the paper builds a primary model of a hydraulic structure by using Civil3D,and the model attributes was expended by data expansion.Secondly,the paper refines the model and extracts the model geometry information through Dynamo to create a Model Information Base.Moreover,the relevant specification provisions are parsed,and the components are classified and coded according to the standard.Then they are stored in the SQL Server database to create a rule knowledge base.Finally,the rule knowledge base and the model information base are connected,so as to realize the compliance check of the hydraulic BIM model.The method proposed in the paper greatly improves the efficiency and accuracy of the compliance inspection of hydraulic structure design and reduces the difficulty of development work,which lays the foundation for promoting compliance inspection for hydraulic structural designs.
