| 摘 要： | 通过野外取样室内试验、野外渗水试验、抽水试验等方法,确定出第四系孔隙水含水层渗透系数0.10~0.11 cm/s,为透水层,是场区产生渗漏的主要地层,并通过垂直与水平渗漏定量计算确定该区应进行防渗处理。针对渗漏特点重点提出了土工膜防渗和截渗墙防渗2种设计方案,并从工程造价、防渗效果、施工技术难度等方面进行了对比分析,确定了截渗墙防渗设计为较优设计方案。

| Abstract: | Through office experiment,penetration experiment in the field and pump experiment,it is determined that the penetration ratio in Quaternary aquirer is 0.10~0.11cm.It is the main strata of happening penetration.Through meaurement on verticle and horizontal and penetration quantities,it is determined that impervious conduction should be carried out in this area.Pointing to impervious characteristics,2 kinds of impervious plans are determined,they are geotechnical membrane and penetration preventing wall.Through contrast and analysis on cost,penetration effect and technical difficulties in construction,it is regarded that penetration preventing wall is the best plan. |

| Keywords: | Penetration preventing penetration by using geotechnical membrane penetration preventing wall Jiaonan in Shandong province |
