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”。 ]lB3qEn<
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 =~W0 ~lxX
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,) An8%7xa7
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! 9HJ'p:{)
请问楼主有什么建议吗?希望楼主能抽空帮小弟看下!谢谢! Ah" 'hFY
