太原市地面沉降的计算与预测

Computation and prediction of the land subsidence in Taiyuan

摘要: 为分析太原市地面沉降,对太原市区进行了地质模型概化,建立了太原市区大规模开采地下水引起地面沉降的数值计算模型,同时对研究区内的地面沉降进行了预测。分析结果表明,太原市地面沉降主要是由于集中开采深层承压含水层引起的。

Abstract: To analyze the cause of land subsidence in Taiyuan,geologic model of Taiyuan City is generalized.A numerical model for computing land subsidence induced by extracting groundwater is developed.At the same time,the land subsidence of research region is forcasted.The results indicate that the land subsidence is mainly induced by the reduction of water level in deep water-bearing strata.
