图形驱动式桥涵结构物特征点坐标计算研究

Study of Graphic-Driven road and bridge-culvert feature point survey construction

桥涵结构物特征点坐标计算是路桥施工测量计算的重要内容,其计算既要涉及线路平面线形数据、桥涵结构物平面布置等信息,同时还需要正确处理线路平面中线与桥涵结构物之间的工程关系。针对现有桥涵结构物特征点坐标计算方法存在的问题,本论文较系统分析了线路中边桩坐标计算理论,并介绍了现计算机求解桥涵结构物特征点坐标的线路平面中线模型及桥涵结构特征点坐标计算的实现原理。

The calculation of bridge-culvert feature point is very important in road-bridge construction survey ,in which,horizontal alignment data ,bridges and other structures layout,and the engineering relations between the center line and the bridge-culvert structures are involved.In view of the existing problems in feature point coordinate calculation of bridge-culvert structures ,theory of center and side stake coordinate calculation are analyzed systematically,and the implementation principles of feature point calculation in bridge-culvert structure with computer are introduced.
