带缓和曲线的特大桥坐标计算及放样方法

The Coordinate Calculation and Layout Method for Especially Big Bridge with Connecting Curve

介绍一种带缓和曲线的特大桥桥墩在测量坐标系下的坐标计算及桥墩放样方法 。

The article introduces piers of bridge coordinate calculation in the surveying system and methods of layout survey for piers of bridge. Furthermore, a theory and a practical method gained under plan polar coordinate are put forward and the use of the Leica electronic total station in the layout survey of the piers of bridge are put forward.
