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。
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 rationality of reinforcing the dam with seeppoof wall were analyzed. The research results provided reference for the design of reinforcement and danger removal of the embankment dam.
