水准平差常用的定权方法有按测段距离定权和按测站数定权两种。介绍了这两种定权方法的原理,比较了水准平差中以每km高差中误差和每测站高差中误差作为单位权中误差定权的特点,以实例计算分析说明了建筑沉降观测中水准平差定权方法的合理选择。 Level adjustment methods commonly used in determining the right to measure the distance and the right to determine the number of stations in two. The principle of these two kinds of weighting methods is introduced. The error of per-km height difference and the error of per station height are compared in the leveling to compare the discrepancies of the weights in the unit weights. An example is given to illustrate the settlement of buildings The reasonable choice of the method of fixing the right of adjustment in observation.
