Abstract:
According to the basic characteristics of micro-confined groundwater aquifer and the mechanism of the ground subsidence bringing out grounwater mining,this paper defines the main compression soil horizon and brings out the ground subsidence influence factors by mining the micro-confined grounderwater with a contrastive analysis mothod,and proves the influence degree on bringing out ground subsidence by adopting the qualitative analysis mothod. Combining with the micro-confined groundwater miniing demmonstation engineerings,this paper gains the ground subsidence value by adopting quantitative calculating supposing the groundwater level under the micro-confined aquifer roof-to-floor,and analyses the influence degree on bringing out ground subsidence by mining the micro-confined groundwater by using ground subsidence practical measurement datas.
