- 摘要:
- 黄河上游某滑坡坝由两岸滑坡物质形成，进而形成了天然堰塞湖，附近区域现已成为国家自然保护区核心区。为了对该滑坡坝的渗透稳定性进行较深入的研究，首先通过试验资料确定了坝体与湖积纹泥渗透稳定的可能破坏形式、临界水力坡降和允许水力坡降，在此基础上通过三维数值计算对滑坡坝在正常湖水位与极限湖水位两种工况进行了渗透稳定性评价。具体评价方法为，在每种工况下先评价计算范围内最大水力坡降方向每一格点（计算剖分网格）的渗透稳定性，进而评价整个坝体的渗透稳定性。研究结果表明，在正常湖水位与极限湖水位两种工况下，坝体均不会出现渗
- Abstract:
- A landslide dam located in the Huanghe upriver was formed by two landslides,then formed the barrier lake which is core area of national natural protection now.In order to study the seepage stability of the dam in detail,based on all experimental materials,the authors determined possible damage forms,critical hydraulic slope,allowable hydraulic slope of landside dam and lacustrine varved clay,then adopted three dimension numerical method to assess the seepage stability of landslide dam in two work conditions of mean lake stage and limiting lake stage. Assessing method is that,first,assessed seepage stability of every grid in direction of maximal hydraulic slope in mean lake stage and limiting lake stage,and then assessed seepage stability of the whole landslide dam. The results proved that the landslide dam would not occur seepage stability problems in mean lake stage and limiting lake stage.In limiting lake stage,volume change of dam leakage would be little. The results presented theoretical basis for soil and water conservation of national natural protection,and for construction and running of a downriver large-scale hydropower station.
