Abstract: With rapid development of construction of high rockfill dams on overburden, it is important to understand the seepage of dam foundation. The analysis of monitoring results is of great significance for study of seepage of dam foundation. In this paper, the monitoring results of dam foundation seepage before and after impoundment of Changhe dam are analyzed,worthy reference for recognizing the combined effect of main and auxiliary impervious walls.

Key words: earth-rock dam, dam foundation, seepage, main and auxiliary impervious wall

摘要: 随着在覆盖层上修建高堆石坝的形势迅猛发展,正确认识坝基渗流成为不可忽视的问题,监测成果分析对研究坝基渗流具有重要意义。笔者对长河坝蓄水前后坝基渗流的监测成果进行了分析,对正确认识主副防渗墙联合防渗效果具有参考意义。
