中国地面沉降地质灾害区划方法与实践

Method and Application of Land Subsidence Disaster Regionalization

由于地下水资源的不合理开发利用,我国已在众多地区存在地面沉降和地裂缝问题,为统筹全国地面沉降防治工作,开展易发程度区划是其重点工作之一。本文以第四纪地质、地下水及含水层特征、地下水开采情况作为划分依据,结合现状发育特点,拟定地面沉降和地裂缝易发区的划分方法,并提出防治对策建议。

Land subsidence and earth fissure phenomena occurred in many cities in China these years due to unreasonable development and utility to groundwater resources.With the continuously deepened of monitoring and controlling of land subsidence in these cities,preliminary results and abundant data had been achieved.In order to comprehensive arrange the controlling work of land subsidence in China,land subsidence and earth fissure disaster susceptibility regionalization is one of the most important task in the study of land subsidence.This paper discussed the susceptibility regionalization of land subsidence and earth fissure disaster begined from the study of factors occurred land subsidence.And this paper is the beneficial attempt in susceptibility regionalization of land subsidence and earth fissure disaster.
