摘要

为深入分析水物理化学作用对河床沉积物垂向渗透系数的影响,采用水头下降竖管渗透试验法,对渭河陕西段5处7个实验研究点,共98个试验点位进行原位沉积物垂向渗透系数(Kv)试验,并对其中的21根测管进行室内不同渗滤液条件下的沉积物垂向渗透系数研究。结果表明:自来水条件下的渗透系数大于河水条件下的渗透系数;营养液条件下渗透系数随时间变化呈先减小后增大的趋势;碱溶液对沉积物渗透系数起负作用,碱性越强负作用越大;酸溶液能增强沉积物的渗透性能,但对不同结构、成分的沉积物影响方式不同;河床沉积物渗透系数与河水中碱度呈极显著负相关,与河水的CODMn呈显著正相关。

Abstract

In this study, the effects of physical and chemical reactions of water on streambed permeability were deeply researched. The head down standpipe penetration test was used to test streambed vertical permeability coefficients, conducted at 98 test sites in the Weihe River Basin in Shaanxi Province, and the sediment samples were collected in-situ from the test sites, and they were tested with different aqueous solutions in laboratory. The results showed that the streambed vertical permeability coefficients tested with tap water were much higher than those tested with river water or nutrient solution. The streambed vertical permeability coefficient tested with nutrient solution was decreased at first and then increased. The effect of aqueous alkali on streambed vertical permeability coefficient was negative. Moreover, there was an extremely significant negative correlation between streambed vertical permeability coefficient and alkalinity of river water, but an extremely significant positive one with CODMn.

Key words： streambed; sediment; permeability coefficients; correlation analysis; the Weihe River of Shaanxi Province
