连拱隧道开挖命令流（ANSYS软件），希望对大家有参考价值 [复制链接]

这是一个连拱隧道开挖命令流，是双向六车道大跨度连拱隧道。

支持! 命令写的不错,很简练!

000000000000000000

命令流看不明白，兄台是否有图像界面的全部过程？我想学习一下。谢谢。

命令流写得不错，大家互相学习

图像操作的没有，如果你安装了ANSYS，可直接运行下，看看生成的过程就可以了。

我用你提供的命令流仿写了一个小间距隧道的模拟，，怎么老出现下面的错误啊？ br_D Orq|  
求解初始地应力，老是出现问题："L-2 norm of,residual force overflow,this may be caused by pred,on and  birth/death elements,please use pred,of and try again " G5'HrV  
希望楼主能帮忙解惑！！

能否将你的命令流上传看看？

谢谢楼主的回复，，这个问题我已经解决了，问题是激活土的塑性时，命令流tbdata,1,cr,fir 把“1”错弄成了“i”。 kSH|+K\M4  
不过现在又有新的问题了：在第二步开挖左隧洞求解时,运行一段时间，求解自动停止，也没出现提示“错误”,也没有说"求解已完成"，，开始我以为是土的参数太取低了（分析的是5级围岩），把各参数适当的提高一点后，这一步可以解出结果了，，可到了第三部开挖右洞时，又出现的同样的问题 @G:aW\Z  
请问这是出了什么问题啊？ （我与楼主分析的不同之处在于，在开挖后，我加了应力反转，） "I)`gy&  
是解不收敛吗？ 还是网格划分有问题？ 我觉得即使是围岩太差，也应该能求出结果的啊！ {G(N vf,K]  
  请问楼主有什么建议吗？希望楼主能抽空帮小弟看下！谢谢！ d6;"zW|Ec
