摘　　要：文中补充了两项内容:(1)验证了应用平面杆系有限元法程序也能分析混合型(抗扭支座与点铰支座 兼有)连续弯箱梁桥的截面内力;(2)找到了另一种更简便的方法来计算该类桥型中两个特殊截面(跨中和中支点 截面)的内力。In this paper two contents are replenished:(1) it is verified that cross sectional forces of continuous curved box girder bridges, installed not only anti-torsional bearings but also point-hinge bearings,may be analysed by the plan element computer program; (2) the orther simplest method calculating the internal forces for two types of special section(midpoint of spans and middle supports of these bridges) is obtained.
