文中探讨了由双透水层所组成含水层的排水计算问题,下层的厚度比上层大很多倍.在上层中设有等距布置的水平排水管系列.计算时认为下层厚度为无限大,水流大致位于排水管中心,排水管单位长度上的流量等于 Q.在解这个问题时,引用了阿维里扬诺夫和瞿兴业在参考文献中所采用的假定,并用汇-源点列迭加法求出渗流区中渗透速度的分布.得出了确定排水管流量的公式,应用这些公式探讨了双层土对于排水管作用的影响.到目前为止,对这个问题已知的解是文中所求得解的局部情况. In this paper, the drainage calculation of aquifer composed of double aquifers is discussed, the thickness of the lower layer is many times larger than that of the upper aquifer, and the horizontal aqueducts are arranged at equal intervals in the upper layer. At the center of the drain, the flow per unit length of the drain equals Q. In solving this problem, the assumptions used by Avilianov and Qu Xingye in the references are quoted, The distribution of the infiltration velocity in the seepage zone, the formula to determine the flow of the drainage pipe, and the influence of double soil on the drainage pipe were discussed by using these formulas. So far, the known solution to this problem is obtained from the text Solution of the local situation.
