【摘要】 临沂某水库是一座病险水库,为确保大坝安全和水库的正常运行,需对大坝进行除险加固。文章利用非线性动力有限元法,对大坝及坝基的抗液化安全性能进行了分析,得出了可能发生液化的部位;在此基础上,提出了相应的加固措施以确保大坝在地震作用下的稳定,结果可为设计提供参考依据。更多还原

【Abstract】 The paper considers a reservoir in Linyi,which is dangerous.To guarantee the dam security and normal operation of the reservoir,reinforcement must be carried out to eliminate the dangers.The nonlinear and dynamic finite element method is used to analyze the anti-liquification ability of the dam and its base.As a result,the possibly liquified places are obtained.Based on the outcome,corresponding measurements for reinforcement are proposed.The conclusion can provide references for the dam design to guarantee the dam stability under seismic conditions.更多还原
