| 摘 要： | 笔者探讨了基于 Ｂ Ｐ 神经网络的横断面填挖方信息提取方法． 该方法可快速地得到任一路线中桩处在不同填挖高度 Ｈ 时的横断面填方面积 Ａｆ 和挖方面积 Ａｃ 的近似值， 并可将 Ｈ～ Ａｆ 及 Ｈ～ Ａｃ 关系图线加绘在纵断面图上， 以便掌握全线或某一区间的填挖方分布状况， 为纵断面拉坡设计提供依据． 该方法易于在 Ｃ Ａ Ｄ 系统中开发实现， 以提高勘测设计自动化、智能化水平．

| Abstract: | BP neural network based on highway cross sections fill and cut information obtaining method is researched.The approximate fill area A\-f and cut area A\-c with different heights of fill or cut H at an arbitrary stake can be calculated quickly by the method,and the diagrams H～A\-f and H～A\-c can be drawn on highway longitudinal profile drawing for better knowledge of the fill and cut distributions of the whole route or a section,which are very helpful to highway longitudinal profile design.The method is applied easily in highway CAD system to enhance the automation and intelligence of highway survey and design. |
