地面沉降是一种危害性严重的环境地质灾害。本文重点分析了开采地下流体、开采地下矿体及地震液化、深大基坑工程引起地面沉降的机理,并结合上海、西安等地区的地面沉降研究与治理课题,针对几种典型成因的地面沉降提出了预防和治理的工程对策。对我国的地面沉降治理具有实际的指导意义。
Land subsidence is a serious environmental and geological disasters. This paper focuses on the mechanism of ground subsidence caused by the exploitation of underground fluids, the exploitation of underground ore bodies, seismic liquefaction and deep foundation pit engineering. Combined with the land subsidence research and governance issues in Shanghai and Xi’an, the ground subsidence of several typical causes Put forward the prevention and management of engineering measures. It has practical guiding significance for the land subsidence governance in our country.
