摘　　要：在北运河典型地段设置两组剖面,通过对两组剖面上地下水水位和水质的观测分析,以及采用模型质点追踪方法,研究了北运河典型地段河水污染对地下水环境的影响范围。结果表明:污染河水对地下水的影响带分布在沿河道向两侧展布约200 m;污染河水对地下水的影响范围与地层岩性有关,在黏性土为主的地层影响范围明显小于以粉细沙为主的地层;污染河水对地下水的影响范围与河水流动的形状有关,在弯度较大的地段,影响范围较大,而且向河岸的一侧倾斜,而在相对平直的地段,影响范围相对较小。Setting two group profiles in the North Canal typical section, basing on observation and analysis of groundwater level and water quality of the two groups of section, and proposing model particle tracing method, the incidence of groundwater environment caused by river pollution of typi- cal section in North Canal were studied. The results show that the incidence cover about 200 m wide along two sides of the river and it is related to lithology of stratum, meanwhile, the influence in cohesive soil strata is significantly smaller than that of in silty sand strata. The incidence of pollu- tion river water on groundwater is related to the shape of river course, bigger the bending, larger the scope, and lean to one side of river, while the incident shows smaller in relative straight river course.
