摘　　要：以济宁某燃煤电厂灰场为例,查明了正在运行中的灰场周围地下水水位、水质现状,通过时间和空间的数据对比,分析了灰场渗漏对地下水环境的影响,指出平原灰场渗漏距离与土层岩性密切相关,黏性土层中灰水渗漏对地下水的影响距离在1 km左右,对水位的影响距离略大于对水质的影响距离。根据场区地层结构和水文地质条件,提出了具体的防渗方案,对正在运行中的灰场可采取在灰水中设截渗槽垂直(坝轴)防渗等措施,可基本解决灰场的渗漏影响。Using an ash field of a coal-fired power plant in Jining as an example, the underground water level and water quality near the operating ash field were investigated. On the basis of spatial and temporal variation of the data, the influence of the plain ash field leakage on the groundwater environment is discussed. The results show that the rock properties greatly influence the leakage distance. The leakage distance was around 1 km in the clay layer, and the distance related to water level was slightly larger than the one Mated to water quality. According to the ash field＇ s stratum structure and the hydrogeologieal eonditions, seepage prevention measures are presented, including building a seepage-intercepting trench in ash water.
