摘要
北京市长期过量开采地下水造成地下水位持续下降,从而引发地面沉降快速发展。利用北京天竺地面沉降监测站长时间序列下分层地面沉降及对应含水层组地下水位监测数据,建立了二者间的多元回归模型,并用实际监测数据验证了该模型的预测效果,据此确定了天竺站的主要沉降贡献层及对沉降影响最大的含水层主控层位。研究成果可为合理调整地下水开采层位以及开展地面沉降防控工作提供科学依据。
Groundwater over-extraction in Beijing causes continuous decline in groundwater level and rapid development of land subsidence.The time-series data of layered subsidence and groundwater level in the corresponding aquifer at the Tianzhu ground subsidence monitoring station were used to develop a multiple regression model.The model was verified based on the observed data.On the basis,the main subsidence layer and main controlling aquifer which has the maximum effects on the land subsidence at the Tianzhu station were determined.The research results can provide scientific reference for the reasonable regulation of groundwater extraction layer and prevention of land subsidence.
