摘　　要：在精密工程施工建设中,用全站仪建立高精度边角网方便、有效。针对边角网数据处理过程中,一般只侧重于平差函数模型的建立,而忽视随机模型合理性的统计检验这一不足,结合边角网在核电施工控制测量中的应用实例,对平差中随机模型的统计检验过程及根据检验结果改善整个数学模型质量进行了详细的探讨。During the construction process of high precision engineering,triangulation network measured by total stations is still a convenient and an economical method for positioning in the project or locating its equipment＇s positions.Most of the conventional methods pay more attention to build a functional model to get the final results such as coordinates and their precision,while the random model＇s statistical test has been neglect,so how to process the random model test and improve the quality of the whole mathematics model have been clarified in details.
