中文摘要：
随着GPS定位技术的发展，目前国内一些远海特大型工程，主要是特大型桥梁的建设正迅速展开。远海工程的测量定位都得依靠GPS定位技术。由于海上施工放样的特殊性，在针对远洋工程施工的特点和技术要求的基础上。进行了施工放样方案选择和精度分析。通过在杭州湾跨海大桥的实践，摸索出在GPS静态测量的基础上用全站仪等常规测量仪器进行施工放样的方法，它能保证测量放样工作的速度和测量放样的精度。
英文摘要：
With the development of positioning technology of GPS, some large engineering in the offshore, especially some large bridge are built now, these constructions all depend upon the positioning technology of GPS. As the Particularity of setting out in the sea, we compared several schemes and did analysis of Accuracy. After the application of GPS static survey and total-station instrument in the construction setting-out of bridge in Hangzhou gulf, it can be concluded that this method can guarantee the speech and accuracy of construction survey setting-out
