西藏满拉水利枢纽工程土心墙堆石坝设计

Design of rockfill dam with earth core in Manla water complex of Tibet

满拉水利枢纽工程大坝为土心墙堆石坝,防渗心墙采用宽级配砾质土,心墙反滤采用天然砂砾料,并以肥心墙、厚反滤的形式成功地解决了渗透稳定问题。文章介绍了大坝的剖面设计、坝体材料分区、坝坡抗震稳定处理措施、基础处理设计以及实际运行等情况。

The dam of Manla water complex is the rockfill dam with earth core. The impervious core is formed by width gradation rudaceous soil. The filter is formed by natural sand and gravel. The seepage stability is solved by width core and thick filter. The paper introduces the design of dam profile,dam material subzone,measures of dam slope earthquake resistance stability,design of foundation treatment and practical operation.
