苏锡常地区地面沉降监测方法体系建设

运用精密水准测量、自动化监测、GPS测量、In SAR监测、光纤监测等多种技术手段开展了苏锡常地区地面沉降监测工作。随着地面沉降时空动态的不断演变,不同监测技术手段的应用效果出现较大差异,需要探讨动态变化的地面沉降条件下不同监测方法的适用性,并以此建立更为高效、可靠的监测方法体系。笔者在总结以往工作基础上,对所使用的方法进行了梳理和总结,分析了不同方法的优缺点及其适用性,提出应根据工作程度实施各种监测技术方法搭配及集成应用的监测方法体系的结论。

Research on monitoring method system of land subsidence in Suzhou-Wuxi-Changzhou area

By using the methods of the precise leveling，automatic monitoring，GPS，InSAＲ，optical fiber monitoring and other technical means，the authors made the monitoring studies for the land subsidence in Suzhou-Wuxi-Changzhou area of Jiangsu Province．With the land subsidence in spatio- temporal dynamic evolution，the application effects of various monitoring technologies reflect great differences． It is necessary to discuss the applicability of different methods，and reliable method system for monitoring ground subsidence must be established． Summarizing the historical monitoring work，the study analyzed the advantages and disadvantages of different methods， and proposed for an integrated application system to implement various monitoring methods based on the previous work．
