江苏省地质灾害与防治探讨

DISCUSSION ON THE GEOLOGICAL HAZARDS AND ITS PROVENTION IN JIANGSU PROVINCE

江苏省地质灾害类型除地震外，主要有地面沉降、滑坡、地下水水质恶化、地面塌陷等几种。地面沉降是因为长期过量开采地下水而引起，主要发生在苏州、无锡和常州；滑坡多为人类工程活动使土体稳定性遭到破坏所致，主要发生在南京和镇江地区；地下水水质恶化是因过量集中开采地下水所致，主要发生在苏州、无锡、常州、南通和徐州地区；地面塌陷是由矿区地下水疏干而造成，主要发生在铜山县、南京和徐州等地的煤矿采空区。江苏地质灾害主要分布在工业集中、经济发达、人口密集的城市和工矿区。根据江苏地质灾害类型多、分布广等特点，必须重视地质灾害的调查研究，这将是国土规划和城市规划中的一项重要工作。

The geological hazards in Jiangsu Province,besides earthquake,falls into types such as the ground subsidence,landslide,groundwater pollution,ground collapse etc.The ground subsidence caused by the longterm over extraction of groundwater occur mainly in Suzhou,Wuxi and Changzhou;the landslide caused mostly by man′s engineering activity impairing earth stability occur mainly in Nanjing and Zhenjiang areas;the groundwater pollution related to the overextraction,is much more serious in Suzhou,Wuxi,Changzhou,Nantong and Xuzhou cities;the ground collapse produced by the drainage of groundwater in mining regions occur mainly in Tongshan county,Nanjing and Xuzhou.The geological hazards in Jiangsu Province are mostly located in the well-developed industrial and mining cities and areas densely populated.It is necessary to investigate and study the geological hazards, and these work should be regarded as a fundamental work in land and municipal plans.
