摘要
通过对东营市城区地面沉降监测数据的分析,得出东营市城区地面沉降的主要影响因素是长期开采石油、天然气、深层地下水,使地层应力增加产生压缩;新构造运动、全球海平面上升、欠固结土自然沉降以及地面荷载是地面沉降的次要影响因素。
Through analysis on monitoring datas of land subsidence thoroughly in Dongying district, it is concluded that the main factors caused the land subsidence are oil and gas exploration and ground water extraction in long time which caused depression of reservoir stress; while other factors, such as Cenozoic tectonic movement, rising elevation of the sea water, natural compaction of the unconsolidated soil and ground-loadings also play an important role.
