摘要
随着现代交通运输体系的发展,线路工程规模日趋扩大和繁杂,传统二维设计稍显滞后,三维正向技术应运而生。通过研究导线法计算原理以及OpenRoads Designer二次开发流程,采用数据库技术,基于面向对象编程,结合自主算法,开发出一种新的导线法,核心思想为确定曲线参数后,将原点处求解缓和曲线、圆曲线通过平移等效替代至实际交点处。工程案例表明,相较于平台内置方法,简化圆曲线参数输入、特征定义选择等4个步骤,新增交点拖拽、导线平移等5个功能,提高了设计效率,可以衔接后续三维模型创建。为OpenRoads Designer平台下二次开发提供一定参考价值,对于加快数字化转型、相关三维正向设计软件开发提供借鉴意义。
With the development of modern transportation system,the scale of alignment engineering is expanding and complex,traditional two-dimensional design lags slightly,and three-dimensional forward technology has come into being.By studying the calculation principle of traverse method and secondary development process of OpenRoads Designer,using database technology,based on object-oriented programming idea,combined with independent algorithm,a new traverse method was developed,its core idea is that after determining the curve parameters,the transition curves and circular curves solved at the origin are equivalently replaced to the actual intersection points through translation.The engineering case shows that compared with the built-in method of the platform,simplifying four steps such as circular curve parameter input and characteristic definition selection,and adding five new functions such as intersection points dragging and alignment translation,the design efficiency is improved,and the subsequent 3 D model creation can be connected.It provides certain reference value for the secondary development under the OpenRoads Designer platform,and provides reference significance for accelerating digital transformation and related three-dimensional forward software development.
