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。

Abstract: | Gr oundw ater ov er2ex traction in Beijing causes continuous decline in g roundw ater level and rapid dev elo pment of land
subsidence. T he time2series data of layered subsidence and g roundw ater lev el in the co rr esponding aquifer at the T ianzhu g ro und
subsidence monitor ing station wer e used t o dev elo p a mult iple reg ression model. The model w as verified based o n the o bser ved
data. On the basis, the main subsidence layer and main contr olling aquifer w hich has the max imum effects o n the land subsidence
at the T ianzhu statio n w ere determined. The research results can pr ov ide scient ific refer ence for the reasonable reg ulatio n of
