摘要
通过对大榭第二大桥首级GPS控制网的网型设计、埋设方式、观测形式、平差方法等方面进行阐述,总结出小区域内利用强制约束边平差方法的实用性、高精度性等特点,为类似工程提供经验。
By describing the network design,embedding method,observation form and adjustment methods of the first class GPS control network for the Daxie second bridge,the paper sums up the practicability and high precision characteristics of the adjustment method by using the constraint edge in small areas,and provides the experience for similar projects.
