大型公路桥梁曲线段三维测设数据实时解算方法及应用

REAL-TIME CALCULATION METHOD OF 3D SURVEYING DATA FOR LARGE HIGHWAY BRIDGE CURVE AND ITS APPLICATION

该文结合南京长江二桥复杂的曲线段施工 ,讨论其三维测设数据的计算模型及解算方法 ,编制相应的计算程序 ,为现场测设提供有效的计算方案 ,从而指导桥梁曲线段的施工测设 ,提高施工速度和保证工程质量。

Combining with the practice of the construction of complex curve in Nanjing Second Yangtze River bridge,the paper studies the calculating model and resolving method of the 3D surveying data, compiles corresponding calculating program, and offers an effective calculating scheme for the practical field surveying, so that it guides the construction survey of bridge curve, speed up the construction and ensures the quality of the engineering project.
