| 摘 要： | 地面沉降作为一种广泛的地质灾害,不仅对地面设施造成很大的破坏,而且也会使地下环境发生变化。从太原市地下水开采历史与地面沉降演变历史总体上相符可以看出,太原市地面沉降是由于过量开采中深层孔隙地下水引起地下水位急剧下降造成的。随着2003年太原市采取关井压采及引黄入并等一系列举措以来,地下水位呈现回升的趋势,地面沉降速率随之减缓。

| Abstract: | Land subsidence,as geological hazards,not only damages ground facility,but also changes underground environment.It can be known that land subsidence of Taiyuan City is caused by the ground water table dropping as groundwater exploitation.The ground water level is recovered with ground water wells closed and the Yellow River water has been used as supply for the city since 2003,and land subsidence rate also is slow down now. |
