摘要
结合近年来城市地面塌陷的频繁出现,分析其渗透变形在地面塌陷中的致灾机理,提出控制措施.结果表明:要控制地下水渗透变形对城市地面塌陷的影响,可以从控制地下水的来源,限制过大的水力坡降以及管理不良地质体形成三个方面来加以管理.
With the frequent occurrences of ground collapses in cities in recent years, the disaster-causing mechanism of seepage deformation in the ground collapses is analyzed, then the control measures put forward. And the results show that, in order to control the influences of groundwater seepage deformation on ground collapses in the city, it could be managed from three aspects as follows： source control of groundwater, restricting the hydraulic gradient in a appropriate range and preventing the formations of unfavorable geological bodies.
