降落漏斗区流场的灰色数值模拟方法研究

对地下水降落漏斗区流场进行灰色数值模拟时,应充分考虑漏斗区内水流的流向问题。由于流向的不同,所建立的方程也有差异。基于这一思想,在建立了地下水流基本灰色有限差分方程的基础上,探讨了降落漏斗区的灰色数值方程的求解方法;并对武安市东部水源地进行了模拟。模拟结果表明,所提出的解法具有很好的应用效果,从而验证了这种新的模拟方法的正确性。对开展地下水降落漏斗区的地下水资源评价和水环境保护具有积极的指导意义。

A Study of Grey Numerical Simulation Method for the Flow Field of Groundwater Depression Cone

It should be taken into full account of water's flow when the study of grey numerical simulation for the flow field of groundwater depression cone. On account of diverse water's flow, there are diversities among the built equations. Based on the thought above, setting up the fundamental grey finite difference equation of groundwater, the solving method of grey numerical equations of groundwater depression cone was discussed. And by means of simulating and solving method to the water source in Wu'an, it was demonstrated that the built model was reasonable and scientific, which confirmed the exactness of grey simulation method. These conclusions have certain guidance significances to study the grey numerical simulation method for the flow field of groundwater depression cone and design the yield in groundwater depression cone.
