| Abstract: | The mechanism of piping was firstly ananlyzed.Then,the current status of study about the calculation model of piping was introduced.From the pint of continuum damage mechanics,the damage seepage differential equations of the piping were derived,and the characteristics of evolution on porosity rate and permeability coefficient were discussed.Which provides a new method for the mechanism study of piping seepage. |
