天津市地下水开采对地面沉降影响的多元回归分析

地下水的过量开采是天津市引起地面沉降的主要原因。因此天津市提出了“压缩地下水开采量”、“地下水人工回灌”、“调整地下水开采层次”等控制地面沉降的3大技术措施。经过多年的努力，控制地面沉降效果明显。如何解决地下水开发与控制地面沉降的关系，更好的贯彻这3大技术措施，是该文编写的初衷。即在开采同样地下水量的情况下，如何使地面沉降量最小；或在地面沉降量容许的情况下，如何开采最大量的地下水。压缩地下水开采量是治理地面沉降的根本措施，亦即如何压缩采水量或调整开采层次会达到最好效果。论文对天津市某区各个地下水开采层的多年累计开采量、累计沉降量进行数据统计分析，建立了该地区累计沉降量及各个地下水开采层的多元相关方程。在此基础上，分析了各个地下水开采层对地面沉降影响的相关程度。以此为该区控制地面沉降的提供依据。

Effect of groundwater exploitation on land subsidence in Tianjin using multiple regression analysis method

The mostly reason of land subsidence due to groundwater excessive mine in Tianjin city. The governmentconstitutes three technologies to control subsidence; reduce groundwater mine quantity, grounder water circumfluence and adjust mine stratum of groundwater. Through work hard, control land subsidence gain visible effect. How to solve the relation of the groundwater development and the control of land subsidence, how to good execute the three technology, is this article＇ s intention. In other words, how to make the minimum subsidence, under the condition of the same groundwater mines, or how to mine the most groundwater, under the condition of the permissible subsidence; the deal of compressing the groundwater mines is a basic measure to control land subsidence ground sink to decline, but how to compress or adjust mine stratum of groundwater will attain the best result. This article use the date statistic between accumulative total groundwater mine quantity of individually groundwater mine stratum and accumulative total land subsidence quantity some years in some region Tianjin City, presented more element mutuality equation between them, and analyze mutuality degree of groundwater mine effect on land subsidence, this article supply gist in order to the government control land subsidence of this region.
