【摘要】 本文提出了应用带条件的间接观测平差进行水平形变网的动态平差方法。研究了点位运动的数学模型,起算条件的类型和数量,网的形亏和秩亏现象,计算的方法和成果的精度估算等问题,并给出了具体的算例。 本方法可用于各种类型的水平监测网。特点是能充分地利用所有的观测资料,特别对那些延续时间长,观测断续进行,难以分期平差的网,效果更佳。并且由于引入了突变参数,解决了不连续观测中点位突变造成的困难。更多还原

【Abstract】 In this paper, a dynamic adjustment method monitoring the horizontal deformation is suggested by the adjustment of observation equations with condition equations.The problems about the models of moving stations, types and numbers of condition equations, configuration and data defects, the way of calculation and accuracy estimation are discussed. Then a numerical example is given.This method is characterized by effectivelly utilization of all observational data, especially will give the best results for the networks which can not be adjusted by steges, because different parts of a network might be observed during distinct periods withinavery long time. It is possible to overcome the difficulty caused sudden movements of stations during uncontinuously observing time to introduce sudden change parameter.更多还原
