摘要
本文从采空塌陷区地表形变监测手段入手,分析传统形变监测手段(如水准、GPS、常规D-InSAR等)的不足,详细介绍了PS-InSAR技术原理、优缺点及应用现状。最后通过总结北京地区采空塌陷变形特征,并针对PS-InSAR技术的特点和局限性进行可行性分析,最终提出门城镇地区适宜采用PS-InSAR技术进行地表形变监测。
In this paper,deficiencies of traditional deformation monitoring techniques such as leveling and GPS as well as conventional D-InSAR technique are analyzed for their application to deformation detection of mining collapse areas.Detailed introductions are also made to the principle,advantages and disadvantages of PS-InSAR technique and its current applications.Through an analysis of deformation characteristics of mining collapse areas in Beijing and the advantages and disadvantages of PS-InSAR technique,it is concluded that the PS-InSAR technique is applicable in deformation monitoring in the Mencheng Town area.
