摘　　要：盐穴地下储气库通过地下盐矿开采、溶蚀形成的地下空间,进行天然气的储存。在储气库的运营过程中,由于盐岩蠕变,腔体体积收缩会产生地面沉降或地面塌陷。在储气库运营过程中建立地面沉降监测网,捕捉因地层蠕变产生的地面沉降具有重要的意义。详细地介绍了我国第一个盐矿储气库的地面沉降监测,并分析运行过程中的地面沉降变化规律。分析揭示,监测数据与腔体体积的收缩具有较好的吻合性。The underground spacing formed by the salt extractions can be re-used as the natural gas storage facilities.During the operation of the natural gas storage facilities,the ground subsidence might occur as the creep of the salt rock mass and the contraction of the salt rock cavern.It is important to establish an observation network to capture these ground deformations.This paper presents the ground subsidence observation and evaluation results of China＇s first natural gas storage facility in the salt rock caverns.The results indicates that the ground subsidence is closely correlated with the salt rock carven contraction.
