摘要
利用模拟河水渗漏补给地下水的砂箱完成了在不考虑天然堵塞的情况下,不同渗透介质、不同河水深及不同地下水埋深的试验,本文总结归纳了河水渗漏量的影响因素。试验得出:河水深度越大,其渗漏量越大;河床及其周围透水介质的渗透性越好,则渗漏量越大;地下水与河水间的水头差越大,则渗漏量越大,但是存在极大值。极大值出现在河水与地下水脱节阶段,脱节后河水与地下水的水头变化不再影响河水渗漏量。
Experiments with different permeable media, different river water depths and different groundwater burial depths were completed without considering natural clogging by using a sand box that simulates river water seepage to recharge groundwater, and the influencing factors of river leakage are summarized. The test results show that the greater the depth of river water, the greater the leakage;the better the permeability of the riverbed and its surrounding permeable medium, the greater the leakage;the greater the head difference between groundwater and river water, the greater the leakage, but exist maximum.The maximum value appears in the disjunction stage of river and groundwater, after which the change of water head between river and groundwater no longer affects the leakage amount of river.
