| 摘 要： | 本文主要探讨了对承压水层上的单井,以定流量 Q 抽水时造成地面形变的可能机理.抽水形成了降落漏斗,漏斗区域内的动水压力降低导致了水层的沉降,这就等于给水层上的盖层施加了一个横向分布的载荷.若把覆盖层看做一个弹性薄板,因而计算出抽水引起的地面垂直形变、水平形变及附加应力等量值.

| Abstract: | This paper concerns with the possible mechanism of ground surface deformation given rise by pumping of water at a constant rate Q from a pressurized water horizon through a single water well. The pumping of water causes a funnel-shaped region in which the pressure of the flowing water drops and as a consequence, the water-bearing horizon lowers. This is equivalent to apply a horizontal loading force to the layers overlying the water horizon. If the overlying layers are assumed to be elastic thin plates, we are able to calculate both the vertical and horizontal deformation of the ground surface and also the additional stresses, etc. |
