摘要
According to the hydrogeological conditions of the target area,in the area which is very rich in groundwater,three sites – Youkou,Xiebu,Taohua – are selected as sources of emergency water supply.In current situation,the goal is set to meet the demand for domestic water consumption for 3 months(693,000 m3/d) in 2020 in the target area.The GMS software is used to simulate the emergency water supply of the three water sources under the most unfavorable rainfall conditions.After three months of emergency water supply,at Taohua sites,the dewatered aquifers of seven of the wells are more than 2/3 of the original aquifer,with a maximum of 78.67%,a minimum of 35.22%,and an average of 56.48%,which basically meets the demand for emergency water supply;at Xiebu site and Youkou sites,the maximum dewatered aquifer is less than 2/3,with an average of 41.06% and 26.30%,respectively,which meets the demand for emergency water supply.In emergency exploitation,dewatering the aquifer provides more than 90% of total water supply.When current situation is resumed after three months of emergency water supply,the aquifers at Taohua,Xiebu and Youkou sites recover to 89.82%,82.57%,and 85.45% respectively,at the end of the year,which is a prove of their excellent recovery.This shows that Taohua,Xiebu and Youkou sites are suitable for sources of emergency water supply.
