摘要
本文根据天津塘沽区深层地沉观测标观测到的地面沉降数据,分析了深层地下热水开采对地面沉降的影响比例。在分析地热水开采引起地面沉降机理的基础上,通过统计回归方法建立了深层孔隙型地热水开采量与地面沉降量的相关模型;提出了进行地热尾水回灌和建立深层沉降监测网以加强综合研究的防治对策。
Based on the observation data of land subsidence in the layered monitoring hole in Tanggu, Tianjin, the effect proportion of production of geothermal water in deep-seated aquifers to sedimentation is analyze. The principle of land subsidence due to producing thermal water in this area is discussed and the correlative model between the production of geothermal water in the porous aquifers and land subsidence is established with the statistic recursive method. A proposal of prevention and cure of land subsidence by injection of geothermal water and establishment of a monitoring mesh of land subsidence in deep layers is also put forward.
