苏锡常地区地面沉降机理及防治措施

地面沉降是一种危害性严重的地质灾害。由于地下水的长期超量开采导致地面沉降不断加剧。然而人们往往总是忽略了地质灾害与地质模式的内在联系，把大多数原因归结为人类活动。事实上地面沉降的发生不仅与地下水水位下降密切相关，而且还与地层岩性结构、水文地质条件、土的类型、厚度、压缩性的大小、固结历史等因素有关。本文以苏锡常地区为例，对地面沉降的机理进行了分析并提出了防治措施。

The mechanism of land subsidence and its prevention measures in Suzhou-Wuxi-Changzhou area

Land subsidence is a serious geological hazard. The long-term over-exploitation of groundwater caused land subsidence is aggravating, but people often overlook the geological hazard with the geological model inherent always ties to attribute the majority to human activities. In fact, the occurrence of land subsidence is not only closely related to the lowering of the groundwater level, but also the structure and lithological, hydrological and geological conditions, soil type, bed thickness, the size of compression and degree of consolidation. Suzhou, Wuxi and Changzhou in this paper as an example , the author analysis the mechanism of land subsidence for its prevention and control measures.
