| 摘 要： | 从现浇段浇注顺序、后连续预应力筋的张拉顺序和临时支座的拆除顺序三方面研究了简支转连续施工体系的合理工序,从受力角度对不同施工工序进行对比分析,建议现浇浇筑和张拉的合理工序为隔端浇筑、隔端张拉.临时支座拆除的合理工序为"对称拆除". |
| 关 键 词： | 先简支后连续梁 体系转换 支座 |

| Abstract: | The conversion of optimal construction system is studied in terms of the pouring order of cast-in-site segment,tensioning of continuous tendon and dismantling of temporary bearing.Different construction procedures are analyzed from the perspective of force.It is considered that the optimal procedure for pouring of cast-in-site segment and tensioning is interval pouring or interval tensioning,and the optimal procedure for dismantling of temporary bearing is symmetrical dismantling. |
| Keywords: | Continuous beam turned from simple beam System conversion Bearing |
