摘要
从高差差分改正入手介绍高差差分改正理论的原理,并推导该理论的精度模型,指出利用该理论进行改正应满足的条件,目的在于将以前学者简单提及的理论系统化的认识和分析,甚至进行更深的推广;最后介绍其在某大坝变形监测中的应用实例,认为在满足文中提出的适用条件的情况下,该理论完全能利用于具体的监测项目中。
This article started from the revise theory of height-differential, introduced the principles of this theory legibly, and deduced its accuracy model, then the author pointed out the conditions on which it should be used, with the purpose of studying and analyzing it systematically, and spreading it deeply; finally it introduced the applying on one dam monitoring and concluded that, on the right conditions, this theory model can be used to practice.
