摘　　要：采用相关平差算法计算导线网中每个观测值的多余观测分量和各类观测值的内可靠性指标，按统计假设检验理论构成观测值的粗差检测统计量，经过探查指出可能含有粗差的观测值。最后给出内可靠性分析的结果。The authors have adopted the algorithm of the correlated adjustment. According to this method, the redundant observation components of the observations and the norm of the internal reliability of all kinds of observations in the traverse network can be calculated. Based on the theory of statistics and hypothesis test, the statistical components, which are applied to inspect the gross error of the observations, have formed. By means of detection, the observations which may contain the gross error can be pointed out. In the end, the analysis of the internal reliability is put forward. At the same time, the paper gives suggestions on both the design of the traverse network and the point in measurements.
