摘　　要：为了研究济南地区粉质黏土层竖向渗透系数,以济南轨道交通3号线某基坑降水工程为例,通过际降水试验运行参数反演模拟地层渗透性参数,得出开挖范围内的主要土层粉质黏土层的渗透性参数,根据模拟反演计算得出,该区域的粉质黏土层的渗透性远大于勘察报告提供的参数。In order to study the vertical permeability coefficient of the powdery clay layer in Jinan area,this paper relies on a foundation pit dewatering project of Jinan Rail Transit Line 3,uses precipitation test operation parameters to invert and simulate the permeability parameters of the geological strata,and obtains the permeability param⁃eters of the main soil layer,the silty clay layer,within the excavation range.According to the simulation inver⁃sion calculation,the permeability of the silty clay layer in this area is much higher than the parameters provid⁃ed in the survey report.
