摘要
随着人类生活、生产领域的不断扩大,出现了越来越多的大型建筑物和工业设施。由于多种因素的影响,这些大型建筑物和工业设施在运营过程中都会发生某种程度的变形,这种变形在一定范围内往往是允许的,但当其超出一定值时,就很可能会变成灾害。要预防这些灾害的发生,就必须要对建筑物的变形进行监测,分析变形产生的原因,总结变形发展的规律。目前建筑物变形监测技术和方法很多,但GPS定位技术以其高精度、高效益、全天候和不需通视等优点在变形监测中独受青睐。详细介绍了GPS定位系统的形成、定位的基本原理、变形监测网的设计、变形监测方案的实施和变形监测误差的消除,供使用GPS进行建筑物变形监测、观测参考。
In pace with enlargement of human beings＇life and production realm unceasingly, more and more large - scale buildings and the industry facility appear. As a result of influence by many kinds of factor, these big buildings and the heavy facility can have some degree of deformation in the operation process, the deformation in certain range is permissible, but when it surpasses the permissible value, the deformation can turn into disasters. To prevent these disasters, it is necessary to monitor the deformation, analyze its cause and summarize its development rule. At present the building deformation monitoring technology and the method are very many. Because of high accuracy, high benefit and all - weather, GPS localization technology is well liked. This article introduced in detail the formation of the GPS positioning system, the basic principle of the localization , the design of the deformalion monitoring network, the implementation of the deformation monitoring plan and the error elimination of deformation measurements. The work done in this paper give a reference to deformaton monitoring and measurements of buliding by use of GPS technonlogy.
