【Abstract】 For the important action of foundations of highway bridge systems in anti-seismic, in this paper, combining approximate probability reliability theory with specifications in effect, we analysed the anti-seismic grades for every kinds of structure’s foundations acted by“multi-value strength”earthquake, and so recommended objective reliability and suggested the approximate express formulas and partical coefficients in aseismic design We hope it will be consulted for revising specifications更多还原
