Abstract

A 3D hydrological and stratigraphic structure model was built based on strata revealed by geological radar and drilling data to probe into the efficiency of water yield of seepage wells in Mazhen county. The model was identified and verified by pumping test of seepage well and the hydrogeological parameters were determined. Sensitivity analysis of the model parameters unveiled that the horizontal permeability coefficient of the quaternary strata had the greatest influence on the water intake effect of seepage well, while the value of recharge C₁ of river had the least influence on the water intake of seepage well. Moreover, optimization design of the seepage well structure evinced that the angle of altitude of radiant tubes between 20° and 30° and spacing of chambers between 75 m and 100 m will result in a good efficiency of water intake by seepage well.

Key words

seepage well / water intake efficiency / coupled seepage-pipe flow model / sensitivity analysis / angle of altitude of radiant tubes / chamber spacing
