23、。結(jié)合GPS定位測量的各種優(yōu)點，將GPS相對定位技術(shù)引入特大型橋梁控制網(wǎng)的測量和基礎(chǔ)放樣，無論對GPS技術(shù)本身的發(fā)展還是對特大型橋梁測量控制都具有極為重要的意義。本文主要就GPS技術(shù)在特大型橋梁測量控制的應(yīng)用進行了研究。從GPS基本原理出發(fā)，論述了控制網(wǎng)的布設(shè)、特別對橋梁控制網(wǎng)設(shè)計、選點、布設(shè)以及精度分析做了詳細(xì)的論述。并結(jié)合蘇通大橋GPS控制網(wǎng)控制測量和基礎(chǔ)放樣的實例，對GPS在特大型橋梁測量控制中的應(yīng)用進行了分析，得到了GPS相對定
