| 摘 要： | 汤池镇位于两组断裂交汇处，下伏震旦系碳酸盐岩中赋存岩溶热水。每年冬季超量开采地热使地下水位骤降37m，产生真空吸蚀、失托增荷等作用，破坏上覆岩土体结构，周而复始，导致7处地面塌陷。目前塌陷的解除性依然存在，为防治地面塌陷必须减少冬季开采量，严格控制水位降深小于16m。

| Abstract: | Tangchi town sits in the crossing of two groups of fractures. The underlying bedrock consists of Sinian limestone, which contains hot groundwater. Because of excessive pumping of groundwater in each winter, the groundwater table drops rapidly even up to 37 meters, which causes vacuum attraction and other effects. All these effects result in the destruction of structure of soil and rock masses and eventually the surface collapse took place in seven places here. By now, it is still possible for surface collapse to take place here. In order to prevent the surface collapse, the pumping of groundwater in winter must be reduced and the drop down of water table must be controlled to be less than 16 meters. |
