摘要
本文首先采用相关分析的方法 ,探讨了地下水开采与地面沉降的关系 ,得出北京地面沉降主要是由于长期超采地下水所致的结论 ;而后运用Modflow软件 ,建立了基于分布参数的地下水流模型和地面沉降土水耦合模型 ,以北京 1995年开采水平为基础 ,预测了 2 0 0 5年、 2 0 10年研究区地面沉降分布范围。为今后开展地下水开采控制、建立地下水可持续开采模型提供了基础。
Through the correlation analysis the relationship between groundwater mining and ground settlement is discussed.The reason of ground settlement in Beijing is owing to the long-term excessive mining of groundwater.The model of groundwater flow and the soil-water couple model of ground settlement based on the distribution parameters are developed by the software MODFLOW.The distributions of ground settlement in 2005 and in 2010 are estimated based on the average mining in 1995,which lays a foundation for the control of groundwater mining and the modeling of the sustained mining of groundwater.
