摘　　要：基于面向对象方法将施工知识分为控制知识、评价知识和决策知识,以方便施工知识的表达.通过知识类的语义及其层次关系的确定,将知识库中知识的获取任务分解为相对独立的知识类中知识的获取.将施工知识更新的3个层次映射到知识类库中3种层次的知识增长机制(即知识项→知识类→结构施工体系知识),提出了动态连接知识对象的推理机制.这种采用动态链接知识对象的方法提高了大型知识系统的运行效率.Construction knowledge is divided into book knowledge, real projects and expert experience with an object-oriented method to facilitate construction knowledge representation. Knowledge obtaining mission in a knowledge database is divided into three obtaining missions in relatively independent knowledge classes in terms of knowledge class semantics and analytical hierarchy. The three levels of construction knowledge updating are reflected into the three levels of knowledge growth mechanism （ knowledge item→knowledge class→structure construction system knowledge）. A knowledge reasoning mechanism with dynamic link knowledge objects was put forward. The mechanism improves the operational efficiency of large-scale knowledge system.
