Research on capacity of adjustment and storage of underground reservoir at pluvial fan area in front of Qinling mountain based on groundwater injection test and numerical simulation
The implemention of flood intercepting and leakage engineering in front of Qinling mountain and full use of storage adjustment capacity of underground reservoir have important significance to solve the problem of uneven time and space distribution of water resources, ameliorate the shortage situation of water resources in Guanzhong area and improve utilization rate of water resources.In order to further research the function of storage and adjustment of underground reservoir in pluvial fan area ahead of Qinling Mountain, the paper selected the pluvial fan zone of Taiping River to carry out groundwater injection experiment, and used Visual MODFLOW software to carry out numerical simulation to the function of storage and adjustment capacity. The results show that under the four modes of designed storage and adjustment, the average regulation depth is about 10 m, the estimated regulation amount of Taiping River and the pluvial fan in afront of Qinling mountain is 3374.8×104m3, 27.04×108m3 respectively. If recharging is moderately strengthen, the bigger storage adjustment potential can be inspired.
