特大公路桥梁施工测量方法的新探索

A new exploration on survey method of especially big highway bridge construction

阐述了特大公路桥梁施工控制测量的原则、方法及技术要求 ,提出了利用方位交会确定桥梁的构件平面位置的方法以及利用双经纬仪确定桥梁构件标高位置的方法 。

This paper expounds the principles,the ways and the technical demands of especially big highway bridge construction control survey.The methods to determine horizontal position of bridge component using direction intersection principles and the method to determine elevation position of bridge component using two transits are put forward.The three dimensional synchronous setting out in especially big highway bridge construction is realized.
