摘要
分析了管涌发生的机理,介绍了管涌计算模型的研究现状。从损伤力学的角度推导管涌分析的渗流损伤连续性方程,并对孔隙率和渗透系数的演化特性等进行讨论,为管涌机理的研究提供了一种新的思路。
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
