本文应用地下水动力学近似方法,探討了渠道和水庫附近有截渗排水沟时地下水恆定运动的一般問題.渗流区为均貭土地段,不透水层有限埋深.在簡化地下水面为水平直线的基础上,通过保角变換,得到計算渠道和水庫的渗漏量以及地下水位差值沿程分布的关系式.文中引用电拟模型試驗资料,初步論証了截渗排水沟适宜的位置和深度,并对建議的計算关系式进行了驗証.
In this paper, the groundwater dynamic approximation method is used to discuss the general problem of constant groundwater movement when there is a seepage-guttering drainage channel near the reservoir. The seepage area is a homogeneous ground section and the impermeable layer has a finite depth. On the basis of conformal mapping, the relationship between the leakage of channels and reservoirs and the distribution of groundwater level differences is obtained by means of conformal transformation.This paper makes a preliminary demonstration of the suitable location and depth of cutoff drainage ditches , And verified the proposed calculation formula.
