漏斗区地下水埋深与地面沉降关系剖析——以山东昌邑市地下水漏斗区为例

Analysis on the relationship between groundwater depth and ground subsidence in funnel area——Take the funnel area of groundwater in Changyi city,Shandong province as an example

地面沉降是一种可由多种因素引起的地面高程缓慢降低的环境地质现象,严重时会成为一种地质灾害。人类活动和地质作用是造成地面沉降的主要原因,其中地下水超采是最主要的原因。为进一步研究地下水埋深和地面沉降的关系,以山东昌邑市地下水漏斗区为例,在对该漏斗区地面沉降特点进行充分探讨的基础上,对漏斗区地下水埋深和地面沉降的关系及开采地下水引起地面沉降的机理进行深入剖析,研究结果认为:引起地面沉降的原因很多,其中地下水超采是重要的因素之一。长期过量开采地下水会诱发的地面沉降不断加重,漏斗区的形成与地面沉降有着密不可分的联系,整个漏斗区内的地面沉降是受漏斗区中心地下水埋深的变化影响的,变化趋势一致,相关性强。研究结果印证了两者之间的相互关系,对由地下水超采引发的地质环境问题的防治、地下水开发利用监督考核和“三条红线”的制定可提供一定的参考。

Land subsidence is an environmental geological phenomenon that can be caused by a variety of factors,and it will become a geological disaster.Human activities and geological processes are the main causes of land subsidence,among which the overexploitation of groundwater is the most importantFor the further study of embedded depth of groundwater and ground subsidence,the relationship between Shandong Changyi city groundwater funnel area,for example,in the funnel area land subsidence characteristics is fully discussed,on the basis of the embedded depth of groundwater funnel area and the relationship between land subsidence and groundwater researches in the mechanism of land subsidence,and the results of the study think:cause ground settlement for many reasons,including groundwater is one of the important factorsLong-term excessive can cause the rising of land subsidence and groundwater funnel area of the formation of the intimate contact with the ground subsidence,the funnel areas of land subsidence is influenced by the change of the buried depth of groundwater funnel area center,the change trend is consistent,strong correlation between the results of the study confirms the relationship between the two,the geological environment problems caused by groundwater in prevention and control of the supervision and review of the development and utilization of groundwater and three can provide certain reference for the establishment of the red line.
