| 摘 要： | 土石坝的渗流控制是保证尾矿库坝体安全的一项重要措施,也是病险尾矿库整治的主要内容之一。以某矿山病险尾矿库土石坝工程为对象,采用有限单元法,揭示施加塑性防渗墙前后坝体及坝基渗流情况,对比加固前后坝体渗流量和测压管水头的变化,分析了防渗墙加固方案的必要性和合理性,研究成果为土石坝除险加固的设计施工提供了参考依据。

| Abstract: | The seepage control of embankment dam is an important measure to ensure safety of tailings dam,and also is one of major rehabilitation measures for risky tailings dam.Taking a embankment dam for tailings storage in some mine as studied object,the seepage of the dam body and dam foundation before and after constructing a plastic seeppoof wall was revealed by finite element method,the changes in the seepage velocity and water head for the dam body before and after reinforcing were compared,the necessity and r... |
