地面沉降是在自然和人为因素作用下,由于地壳表层土体压缩而导致区域性地面标高降低的一种环境地质现象。德州市是山东省地面沉降发生时间较早地区,地面沉降不仅造成了地面高程失真,而且对城市防洪、交通、建筑物以及农业生产均造成不良现象。本文对德州市地面沉降现状、形成机理、造成的危害、防治措施进行了剖析,旨在为控制地面沉降发生、发展趋势,减少经济损失提供资料依据。
Land subsidence is an environmental geology phenomenon under the action of natural and man-made factors, which leads to the reduction of the regional ground elevation due to the compression of the crustal surface soil. Dezhou is an area where land subsidence took place earlier in Shandong Province. Land subsidence not only caused ground elevation distortion, but also caused unfavorable phenomena in urban flood control, traffic, buildings and agricultural production. This paper analyzes the status quo, formation mechanism, damage and prevention and control measures of ground subsidence in Dezhou City. The purpose of this paper is to provide data basis for controlling ground subsidence, developing trend and reducing economic losses.
