【摘要】 对中小跨径桥梁电子图进行抽象,建立了中小跨径桥梁绘图设计重用模型。该模型将桥梁设计图重用分成4个层次:图形库的形成、桥梁图形知识表示、桥梁图形知识库的形成以及桥梁图形知识的派生。每一层根据桥梁设计绘图的特点,考虑表达能力和求解复杂度,构建子模型;各层子模型通过预定义的接口进行信息的交互,构成最终的桥梁绘图重用模型。该模型通过人工智能算法,动态生成符合设计习惯的新的桥梁设计案例,为桥梁绘图设计重用提出了新的方法。更多还原

【Abstract】 This research develops a methodology and reusing model of draft.This model consists of four parts,such as formation of drawing database and drawing knowledge,data mining of drawing,representation of drawing knowledge,and regeneration of bridge knowledge.Every part was designed according to characteristic of bridge design and draft,and so submodel was developed by analyzing representation ability and comparing complexity.Information Mutual exchanged between each submodel was established by predefined interface.New bridge solution can be achieved by using method of artificial intelligence in the model.This model presented a new way of drawing reuse.更多还原
