岩溶之上覆盖着第四系松散土层时,一般地下水位埋藏浅,且具有统一水面,当地下水位下降或受震动,将发生大规模的地面塌陷。塌陷的时间突然,空间位置难以予测。因而给工、农业、矿山以及交通运输,人民生活带来极大的危害与威胁。这是近年来出现的一个新的岩溶工程地质问题。目前,对地面塌陷发生的机理、勘探及处理都在探索中。本文拟对其发生原因;顶板的稳定性以及工程处理措施等方面进行初
When karst is covered with Quaternary loose soil, the groundwater level is generally buried shallow and has a uniform surface. When the local water table is lowered or shaken, large-scale ground collapse will occur. Sudden collapse of the time, the spatial location is difficult to predict. Thus bringing great harm and threat to work, agriculture, mining, transportation, and people’s life. This is a new karst engineering geological problem that has emerged in recent years. At present, the mechanism of ground subsidence, exploration and treatment are explored. This article intends to its causes; roof stability and engineering measures such as early
