| 摘 要： | 钢筋混凝土和预应力混凝土简支梁桥的经济跨度分别为20m和40m左右。当跨径超过这个范围时,为了降低材料用量和构件吊装安装的难度,应当采取减小跨中弯矩值的其他体系桥梁。实践证明,悬臂体系和连续体系的梁桥,可以作为重要的设计比选方案。

| Abstract: | The economic span of reinforced concrete and prestressed concrete simply supported girder bridge are 20m and 40mrespectively.When span is more than this range,we should adopt to reduce the other system bridges of the mid-span moment values,in order to reduce the amount of material and the difficulty of component lifting installation.Practice has proved cantilever system and continuous beam bridge can be used as an important design scheme. |
