摘　　要：通过介绍GPS测量与传统的测边、测角成果结合在一起,构成复合网进行平差计算,最终求出控制点坐标的实例,阐述了一种高精度控制网的建网及实测方法。通过施测方法和精度对比,证明该施工控制网合理,施测方便,成果精度优良,满足规范要求和技术设计中的预期指标。这一技术可在特长隧洞、超长贯通工程的施工控制网中推广运用。Through adjusting the data of GPS, baseline and angle, the coordinates of control sites are gotten, and a method to construct and measure the high-precision controlling net is introduced here. Contrasting to the method and the accuracy, it is proved that the controlling net is reasonable, the measurement is convenient and the precision is better, thus satisfying for requirement of the standard and design. This technology can be applied widely in the construction controlling net of long tunnels and uhra-long breakthrough projects.
