摘要
地面沉降是一种区域性的缓变型地质灾害,不同地区地面沉降具有相似性又有独特性。本文结合苏锡常地区的实际地质条件．把第四纪地层按不同的沉积类型划分出三类地层结构区,提出用地面沉降响应系数这一指标来评价地面沉降与地下水关系,探讨了不同岩性结构区地面沉降在时间上和在垂向地层空间上的基本规律。
Land subsidence is a gradually-developing regional geological hazard, which shows both similar and unique characteristics in different zones. According to the sedimentary types of Quaternary deposits, the Suzhou-Wuxi-Changzhou area, where land subsidence is serious in China, is classified into three zones of different lithological structures. This paper proposed a new conception called“land subsidence response coefficient”to describe the relationship between land subsidence and groundwater, and also discussed the basic temporo-spatial laws of land subsidence in zones of differ-ent lithological structures.
