摘　　要：针对水利安全监测工程的大坝BIM集成在GIS场景中进行数字化管理时存在几何语义信息丢失、语义映射不明确等问题,本文利用CityGML内置的ADE扩展机制,提出一种水利安全监测语义模型设计方法,对监测大坝的语义信息和属性进行扩展。该模型在与BIM进行语义映射的过程中可以减少几何语义信息的丢失,完善融合模型中语义关系的描述。In view of the problems such as the loss of geometric semantic information and the ambiguity of semantic mapping in the digital management of dam BIM integration in the GIS scene of water conservancy safety monitoring project,this paper proposes a semantic model design method of water conservancy safety monitoring by using the ADE extension function built in CityGML,taking the dam safety monitoring project as an example,to expand the semantic information and attributes of monitoring dam. In the process of semantic mapping with BIM,the new model can reduce the loss of geometric semantic information and improve the description of semantic relationship in the fusion model.
