Crack in concrete dam is a universal phenomenon,so there is a say that no dam did not crack.Cracks in the dam accident,only a few cracks are due to unreasonable structure or uneven foundation settlement,most of them are caused by temperature stress.At present,it is difficult to describe the arch dam cracking state under the widely used arch-cantilever method to calculate arch dam temperature load.For this reason,the article used the ANSYS finite element simulation technology,thought about non-linear concret...
