| 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。

| 关 键 词： | 抗扭支座 点铰支座 翘曲应力 弯矩换算公式 |

| Abstract: | 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. |

| Keywords: | anti-torsional bearing point-hinge bearing waping stress conversion formula of moment |
