| 摘 要： | 随着社会经济的快速发展，黄河三角洲地区普遍发生了地面沉降，已经成为了影响区域社会经济可持续发展的重要因素之一。本文以黄河三角洲地面沉降典型地段—滨州地区为研究对象，以该区2005~2019年年间共计6期地面沉降监测数据为基础，对区内多年来地面沉降发展演变规律进行分析，对地面沉降成因机理进行研究，并根据滨州地下水系统的水文地质条件以及地面沉降机理，概化出滨州地下水系统水位地质概念模型及地面沉降模型。在此模型基础上推演建立滨州地下水开采与地面沉降三维数值模型。利用该模型对地面沉降与地下水位监测数据进行内插外推计算，综合计算结果分析和研究，对地面沉降和地下水动态进行预测预警，从而为黄河三角洲地区地面沉降防治提供依据。

| Abstract: | With the rapid development of society and economy, the Yellow River delta has been suffering from a widespread land subsidence, which has become one of the major factors affecting the sustainable development of local society and economy. We research the typical land subsidence area Binzhou district, basing on the local monitoring statistics from 2005 to 2019 with a total six subsidence cases, and analyze the pattern and formation mechanism of the territorial subsidence over the years. In accordance with the hydro- geological mechanism of the underground water system in the district and subsidence mechanism, we summarize a local underground water hydro- geological concept model and subsidence model. Based on this model, a three- dimensional numerical model for groundwater exploitation and land subsidence in Binzhou is established. By using the numerical model to calculate, we analyze and study the subsidence and underground water level to forecast and set alarm on subsidence and underground water dynamics, thus to provide guidance to prevent and avoid subsidence in the Yellow River delta. |
