摘要
鉴于地基与基础在公路桥梁整体抗震可靠度中的重要作用 ,运用近似概率可靠度理论 ,结合现行规范 ,全面分析了“众值烈度”地震作用下各类地基与基础的抗震可靠度水平 ,并推荐出目标可靠度 ,建议了抗震设计的实用表达式及分项系数 。
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
