Studies On The Equivalent Strength Of Inductive Crack Of Rcc Dams

This paper expatiates on the meaning of the research on equivalent strength of inductive crack of RCC dams. The problem of temperature stress and the measures of control temperature has been generalized; The endanger of crack caused by temperature stress and the essentiality of controlling crack are analysed; Based on the discussion of the measures which are used to solve the problem of temperature stress, the predominance and application foreground of inductive crack is demonstrated; then, the importance meaning and value of the inductive crack research are provided.Emphase of this paper is the examination of the equivalent strength of inductive crack. By analyzing the test results of the penetrated and the non-penetrated inductive crack, the nicety and rationality of the inductive crack formula are validated; the infection rules of weaken degree and equivalent strength are got; the distributing of the strain around the inductive crack is briefly introduced.In the simulation of inductive crack by ANSYS, this paper calculates the stress intensity factor by J-integral method using lots of inductive crack models. Using statistics principles, the result of the examination is proved effective, and the research is developed to get the infection rule of kinds of complications which are influencing the stress intensity factor.The conclusion discussed in this paper has definite referenced value for examination, theory analysis and design of inductive crack.
