摘要
以河北省唐山市某矿山尾矿库坝体为例,利用河海大学自主研发的计算软件Auto Bank,并采用瑞典圆弧法和简化毕肖普法分别计算尾矿库坝体在正常、洪水及特殊运行工况下的稳定性系数。坝体在正常、洪水以及特殊工况下运行,采用两种计算方法计算得出的抗滑稳定性系数远大于AQ2006—2005尾矿库安全技术规程的技术要求,处于稳定状态,为该矿山灾害预防和治理提供了可靠的理论依据及技术支撑。
Taking the mine tailings dam in Tangshan as an example, the AutoBank, which is independently developed by HohaiUniversity, is used to calculate the stability factor of tailings dam under the condition of the normal, flood and special operation.From the calculation results of the two methods, it can be seen that the slip resistance coefficient of dams which are running undernormal, flood and special conditions is much larger than the technical requirements of the ＂Tailings Reservoir Safety TechnicalRegulation （AQ2006-2005）＂. The tailings dam is ina steady state. The calculation results can provide a reliable theoretical basisand technical support for the mine disaster prevention and management.
