基于“区域分解”思想的苏锡常地区地面沉降相关预测模型研究

Research on the correlative prediction model with a regional decompo -sition base of the land subsidence in the Suzhou-Wuxi-Changzhou area

本文在系统分析苏锡常地区地下水开采与地面沉降发展动态及相互关系的基础上,从"区域分解"的思想出发,将研究区按第四纪土层结构进行了合理分区,并分别在各亚区建立地面沉降量与地下水水位相关预测模型。实践表明,该模型符合现阶段苏锡常地区地面沉降研究现状,具有一定的实用价值。

Based on a systematic analysis of groundwater exploitation, development of land subsidence and their interrelationship in the Suzhou-Wuxi-Changzhou area, the structure of the Quaternary soil has been divided reasonably with a regional decomposition method. Correlative prediction models of groundwater level and land subsidence have been established respectively in each subdivision. The practical results show that the model is suitable to the current research of the land subsidence in this area and has a certain practical value.
