五家站试验区地下水运移机制物理模拟试验研究

Study on Physical Simulation Test of Groundwater Movement Mechanism in the Five Stations

通过对五家站试验区水文地质条件的物理模拟试验,其结果反映了天然条件下渗流区含水介质渗流场的分布特征,同时反映了试验区内地下水由补给边界向排泄边界运移的规律。通过模拟试验和计算获得的渗透系数、给水度、降水入渗系数等参数,在数值上接近野外试验数据,为区域地下水资源评价提供了可靠的参数,节约了大量人力、物力和经费。

Through the physical simulation test of hydrogeological condition from the five stations, the result shows their distributed characteristics of the seepage space of the aquiferous medium under the inartificial condition, reflects the movement regulation of groundwater from the replenishment to the discharge borderline. The article is based on the seepage coefficient, water supply and precipitation seepage p＇arameter from the simulation test and its calculation. The value is close to the field test data and provide the reliable coefficient for evaluation of the water resources in the area so that to save a lot of person power, material resources and other cost.
