摘要
开采地下水对于地面沉降影响较大,过量开采地下水会导致地面沉降漏斗,对人民的生活构成了潜在的威胁。本文以德州市德城区为计算背景,基于蒙特卡罗随机性分析方法以及固结理论,采用数值模拟的方式建立三维地面沉降模型,对参数孔隙率进行随机性分析并且对地面沉降量进行分析研究,研究深层地下水开采引发的地面沉降问题,为研究区域沉降现象的治理提出理论依据。
The exploitation of groundwater has a great impact on the ground subsidence, and the overexploitation of groundwater can lead to the ground subsidence funnel, which poses a potential threat to the people's life. This paper takes Dezhou city as the background, based on the monte carlo stochastic analysis method and consolidation theory, the numerical simulation way of 3 d land subsidence model is established, an analysis of the random parameters of porosity and analysis of ground subsidence in this study, the results showed that the impact of when the porosity calculation parameters to meet the change of the lognormal distribution to the settlement, When the deviation coefficient is 30%, the settlement is the most consistent with the monitoring value, most in line with the actual situation, with a certain degree of reliability, The results provide theoretical basis for the treatment of regional settlement.
