摘要
应用有限差分软件FLAC3D建立南芬露天矿拦水土石坝的三维模型,对拦水坝的应力应变和渗流进行了数值模拟,并比较了水位最低和最高时的应力状态。模拟结果表明了坝体的弱应力区、主应力及位移大小值,可改善坝体的稳定性和安全性提供依据。结果还表明该方法可以较好地模拟拦水坝坝体内部渗流场和应力场的耦合作用,较好地评价拦水坝的安全效果,对于类似工程的防渗加固实践有一定的指导作用。
A finite difference software （FLAC^3D） is used to establish 3D model of Nanfen open pit mine,the stress-strain and seepage are simulated,and stress state of the minimum and maximum water lever is compared.Simulation results show the low stress area,the value of principal stress and displacement,which can provide evidence to improve the stability and safety of the dam.The results also show the method can simulate the seepage and stress field in the coupling,can evaluate the safety effect of dam better,which can offer guidance for the anti-seepage reinforcement of similar engineering.
