| Abstract: | This paper makes use of the method of linear elastic fracture mechanics to analyse the stability of the vertical mid crack on the upstream face of Huan-Ren buttress dam. Under the action of the various loads and boundary conditions, the stress intensity factor is calculated by using the isoparametric singular element. The effective crack length method is used to deduce the stable value of the fracture toughness of concrete for the dam. |
