摘　　要：针对混凝土坝浇筑块及其仓面表达中非几何信息表达存在的问题,本文首先以施工工艺流程和分部分项工程为基础进行混凝土坝浇筑块的产品结构分解(PBS)和工作结构分解(WBS);然后建立基于PBS-WBS合成映射的浇筑块特征模型,以基本参数描述浇筑块及其仓面的几何信息,以特征树描述浇筑块及其仓面的非几何信息;最后采用OWL本体语言表达浇筑块特征,实现浇筑块特征信息的存储、查询及更新等操作。案例分析证明,本方法可以提高对浇筑块及其仓面信息认识的全面性和表达的准确性,帮助施工技术人员合理地分配施工任务和调配施工资源。To resolve the problem existing in the non-geometric information expressions of concrete dam blocks,this paper firstly describes the product breakdown structure(PBS)and work breakdown structure(WBS)of concrete dam blocks based on dam construction process and sub-projects.Then,using the PBSWBS composite map,we develop a feature model of dam blocks that describes their geometric information with basic parameters and their non-geometric information with feature trees.Finally,OWL ontology language is used to express the features of dam blocks,and storage,query and update of the feature information are realized.Case analysis proves that this method improves the comprehensive understanding and accuracy of the information of dam blocks and can help construction technicians reasonably assign construction tasks and allocate construction resources.
