| 摘 要： | 本文探讨了抽用地下水对地面形变所造成的影响。文中应用了几个抽水试验实例, 说明了它们在时间上、空间上的相互变化关系。抽水所造成的地下水漏斗区范围内, 不仅能产生垂直形变, 而且在其影响的不同部位, 还形在压缩和拉伸的水平形变。对抽水引起的地面形变与其他因素所造成的地面形变的区别, 进行了视步的讨论。

| Abstract: | Change of ground water level gives rise to ground deformation is concerned in this paper. It describes several actual experiments in-situ of pumping water from wells, indicating the relation between the variation of elevation and the pumping, with respect to time and location. Around the pumping wells and within the limit of a funnel-shaped ground water surface, not only vertical movement, but also horizontal compression and dilatation can be observed. A preliminary discussion has been made in connection with the distinction between ground deformation caused by ground water change and other factors. |
