摘要: 地面沉降是区域性地面高程下降的一种地质现象,一般是由自然因素和人为因素的共同作用导致的。目前地面沉降监测的方法很多,各有优劣。本文结合武进中心城区地面沉降监测系列工程案例,对不同沉降监测方法产生的多源数据进行了分析、对比和融合,使成果兼具各种方法的优点,其不仅能更好地描述地面沉降的现状及预测地面沉降的发展趋势,而且可为后期地面沉降监测提供更加准确且丰富的数据基础。

Abstract: Land subsidence generally refers to a environmental geological phenomenon of a decline in regional ground elevation, which is caused by the soil compression in the joint action of natural and human factors. At the present, we find both advantages and disadvantages among the different monitoring methods of land subsidence. Changzhou-Wujin area is located in the sedimentation section of Yangtze River Delta. This paper explores the case of Wujin central city land subsidence monitoring project. With analysis, comparison and integration of the multi-source data from different monitoring methods, the result combines the advantages of different methods. It not only better describes the present situation and forecasts the trend of land subsidence, but also provides the more accurate and extensive data base for future land subsidence monitoring.

Key words: land subsidence, leveling surveying, GNSS, InSAR, data fusion
