摘　　要：综合应用了 3种计算方法的原理 :( 1)内力增大系数法 ;( 2 )刚接板荷载横向分布系数法 ;( 3)等代简支梁跨长等 ,建立了带悬臂翼缘的整体式钢筋混凝土连续板桥计算模型。它可以应用一般平面杆系的电算程序计算 ,其精度已被空间有限元电算程序的计算结果所验证。因此 ,本模型对于设计人员来说 。Applying synthetically the principle of three methods:(a)increasing coefficient method of interal force in section;(b)load transverse distribution coefficient method for rigid jointed plat bridge;(c)method of equivalent span of simple supported beam,the calculating model for integrative type of reinforced concrete continuous slab bridge with cantilever flange is established.It may be calculated by the plan element computer program,and its precision is proved by the results of space computer program.Therefore this model has practical significance for designer.
